# Constructing general big tuples

GHCs built in tuples can only go up to `mAX_TUPLE_SIZE` in arity, but we might concievably 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.

mkChunkified Source #

Arguments

:: ([a] -> a) | "Small" constructor function, of maximum input arity `mAX_TUPLE_SIZE`
-> [a] | Possible "big" list of things to construct from
-> a | Constructed thing made possible by recursive decomposition

Lifts a "small" constructor into a "big" constructor by recursive decompositon

chunkify :: [a] -> [[a]] Source #

Split a list into lists that are small enough to have a corresponding tuple arity. The sub-lists of the result all have length <= `mAX_TUPLE_SIZE` But there may be more than `mAX_TUPLE_SIZE` sub-lists

Returns all the binding names of the decl. The first one is guaranteed to be the name of the decl.

For record fields mentioned in multiple constructors, the SrcLoc will be from the first occurrence.

Each returned (Located name) has a SrcSpan for the whole declaration. See Note [SrcSpan for binders]
