Module      : GHC.Hs.Utils
Description : Generic helpers for the HsSyn type.
Copyright   : (c) The University of Glasgow, 1992-2006

Here we collect a variety of helper functions that construct or
analyse HsSyn.  All these functions deal with generic HsSyn; functions
which deal with the instantiated versions are located elsewhere:

   Parameterised by          Module
   ----------------          -------------
   GhcPs/RdrName             GHC.Parser.PostProcess
   GhcRn/Name                GHC.Rename.*
   GhcTc/Id                  GHC.Tc.Utils.Zonk

The @mk*@ functions attempt to construct a not-completely-useless SrcSpan
from their components, compared with the @nl*@ functions which
just attach noSrcSpan to everything.

-- GHCs built in tuples can only go up to 'mAX_TUPLE_SIZE' in arity, but
-- we might conceivably want to build such a massive tuple as part of the
-- output of a desugaring stage (notably that for list comprehensions).
--
-- We call tuples above this size \"big tuples\", and emulate them by
-- creating and pattern matching on >nested< tuples that are expressible
-- by GHC.
--
-- Nesting policy: it's better to have a 2-tuple of 10-tuples (3 objects)
-- than a 10-tuple of 2-tuples (11 objects), so we want the leaves of any
-- construction to be big.
--
-- If you just use the 'mkBigCoreTup', 'mkBigCoreVarTupTy', 'mkTupleSelector'
-- and 'mkTupleCase' functions to do all your work with tuples you should be
-- fine, and not have to worry about the arity limitation at all.

************************************************************************

Get all the binders in some HsBindGroups, IN THE ORDER OF APPEARANCE. eg.

...
where
  (x, y) = ...
  f i j  = ...
  [a, b] = ...

it should return [x, y, f, a, b] (remember, order important).

Note [Collect binders only after renaming]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
These functions should only be used on HsSyn *after* the renamer,
to return a [Name] or [Id].  Before renaming the record punning
and wild-card mechanism makes it hard to know what is bound.
So these functions should not be applied to (HsSyn RdrName)

Note [Unlifted id check in isUnliftedHsBind]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The function isUnliftedHsBind is used to complain if we make a top-level
binding for a variable of unlifted type.

Such a binding is illegal if the top-level binding would be unlifted;
but also if the local letrec generated by desugaring AbsBinds would be.
E.g.
      f :: Num a => (# a, a #)
      g :: Num a => a -> a
      f = ...g...
      g = ...g...

The top-level bindings for f,g are not unlifted (because of the Num a =>),
but the local, recursive, monomorphic bindings are:

      t = /\a \(d:Num a).
         letrec fm :: (# a, a #) = ...g...
                gm :: a -> a = ...f...
         in (fm, gm)

Here the binding for 'fm' is illegal.  So generally we check the abe_mono types.

BUT we have a special case when abs_sig is true;
  see Note [The abs_sig field of AbsBinds] in GHC.Hs.Binds

Note [Dictionary binders in ConPatOut]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Should we collect dictionary binders in ConPatOut? It depends! Use CollectFlag
to choose.

1. Pre-typechecker there are no ConPatOuts. Use CollNoDictBinders flag.

2. In the desugarer, most of the time we don't want to collect evidence binders,
   so we also use CollNoDictBinders flag.

   Example of why it matters:

   In a lazy pattern, for example f ~(C x y) = ..., we want to generate bindings
   for x,y but not for dictionaries bound by C.
   (The type checker ensures they would not be used.)

   Here's the problem.  Consider

        data T a where
           C :: Num a => a -> Int -> T a

        f ~(C (n+1) m) = (n,m)

   Here, the pattern (C (n+1)) binds a hidden dictionary (d::Num a),
   and *also* uses that dictionary to match the (n+1) pattern.  Yet, the
   variables bound by the lazy pattern are n,m, *not* the dictionary d.
   So in mkSelectorBinds in GHC.HsToCore.Utils, we want just m,n as the
   variables bound.

   So in this case, we do *not* gather (a) dictionary and (b) dictionary
   bindings as binders of a ConPatOut pattern.


3. On the other hand, desugaring of arrows needs evidence bindings and uses
   CollWithDictBinders flag.

   Consider

        h :: (ArrowChoice a, Arrow a) => Int -> a (Int,Int) Int
        h x = proc (y,z) -> case compare x y of
                        GT -> returnA -< z+x

   The type checker turns the case into

        case compare x y of
          GT { $dNum_123 = $dNum_Int } -> returnA -< (+) $dNum_123 z x

   That is, it attaches the $dNum_123 binding to a ConPatOut in scope.

   During desugaring, evidence binders must be collected because their sets are
   intersected with free variable sets of subsequent commands to create
   (minimal) command environments.  Failing to do it properly leads to bugs
   (e.g., #18950).

   Note: attaching evidence binders to existing ConPatOut may be suboptimal for
   arrows.  In the example above we would prefer to generate:

        case compare x y of
          GT -> returnA -< let $dNum_123 = $dNum_Int in (+) $dNum_123 z x

   So that the evidence isn't passed into the command environment. This issue
   doesn't arise with desugaring of non-arrow code because the simplifier can
   freely float and inline let-expressions created for evidence binders. But
   with arrow desugaring, the simplifier would have to see through the command
   environment tuple which is more complicated.

Note [SrcSpan for binders]
~~~~~~~~~~~~~~~~~~~~~~~~~~
When extracting the (Located RdrNme) for a binder, at least for the
main name (the TyCon of a type declaration etc), we want to give it
the @SrcSpan@ of the whole /declaration/, not just the name itself
(which is how it appears in the syntax tree).  This SrcSpan (for the
entire declaration) is used as the SrcSpan for the Name that is
finally produced, and hence for error messages.  (See #8607.)

Note [Binders in family instances]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In a type or data family instance declaration, the type
constructor is an *occurrence* not a binding site
    type instance T Int = Int -> Int   -- No binders
    data instance S Bool = S1 | S2     -- Binders are S1,S2


************************************************************************
*                                                                      *
        Collecting binders the user did not write
*                                                                      *
************************************************************************

The job of this family of functions is to run through binding sites and find the set of all Names
that were defined "implicitly", without being explicitly written by the user.

The main purpose is to find names introduced by record wildcards so that we can avoid
warning the user when they don't use those names (#4404)

Since the addition of -Wunused-record-wildcards, this function returns a pair
of [(SrcSpan, [Name])]. Each element of the list is one set of implicit
binders, the first component of the tuple is the document describes the possible
fix to the problem (by removing the ..).

This means there is some unfortunate coupling between this function and where it
is used but it's only used for one specific purpose in one place so it seemed
easier.
