{- $matching_overloaded_methods_in_rules

Matching on class methods (e.g. @(==)@) in rewrite rules tends to be a bit
fragile. For instance, consider this motivating example from the @bytestring@
library,

@
break :: (Word8 -> Bool) -> ByteString -> (ByteString, ByteString)
breakByte :: Word8 -> ByteString -> (ByteString, ByteString)
\{\-\# RULES "break -> breakByte" forall a. break (== x) = breakByte x \#\-\}
@

Here we have two functions, with @breakByte@ providing an optimized
implementation of @break@ where the predicate is merely testing for equality
with a known @Word8@. As written, however, this rule will be quite fragile as
the @(==)@ class operation rule may rewrite the predicate before our @break@
rule has a chance to fire.

For this reason, most of the primitive types in @base@ have 'Eq' and 'Ord'
instances defined in terms of helper functions with inlinings delayed to phase
1. For instance, @Word8@\'s @Eq@ instance looks like,

@
instance Eq Word8 where
    (==) = eqWord8
    (/=) = neWord8

eqWord8, neWord8 :: Word8 -> Word8 -> Bool
eqWord8 (W8# x) (W8# y) = ...
neWord8 (W8# x) (W8# y) = ...
\{\-\# INLINE [1] eqWord8 \#\-\}
\{\-\# INLINE [1] neWord8 \#\-\}
@

This allows us to save our @break@ rule above by rewriting it to instead match
against @eqWord8@,

@
\{\-\# RULES "break -> breakByte" forall a. break (`eqWord8` x) = breakByte x \#\-\}
@

Currently this is only done for @('==')@, @('/=')@, @('<')@, @('<=')@, @('>')@,
and @('>=')@ for the types in "GHC.Word" and "GHC.Int".

-- | The 'Ord' class is used for totally ordered datatypes.
--
-- Instances of 'Ord' can be derived for any user-defined datatype whose
-- constituent types are in 'Ord'. The declared order of the constructors in
-- the data declaration determines the ordering in derived 'Ord' instances. The
-- 'Ordering' datatype allows a single comparison to determine the precise
-- ordering of two objects.
--
-- 'Ord', as defined by the Haskell report, implements a total order and has the
-- following properties:
--
-- [__Comparability__]: @x <= y || y <= x@ = 'True'
-- [__Transitivity__]: if @x <= y && y <= z@ = 'True', then @x <= z@ = 'True'
-- [__Reflexivity__]: @x <= x@ = 'True'
-- [__Antisymmetry__]: if @x <= y && y <= x@ = 'True', then @x == y@ = 'True'
--
-- The following operator interactions are expected to hold:
--
-- 1. @x >= y@ = @y <= x@
-- 2. @x < y@ = @x <= y && x /= y@
-- 3. @x > y@ = @y < x@
-- 4. @x < y@ = @compare x y == LT@
-- 5. @x > y@ = @compare x y == GT@
-- 6. @x == y@ = @compare x y == EQ@
-- 7. @min x y == if x <= y then x else y@ = 'True'
-- 8. @max x y == if x >= y then x else y@ = 'True'
--
-- Note that (7.) and (8.) do /not/ require 'min' and 'max' to return either of
-- their arguments. The result is merely required to /equal/ one of the
-- arguments in terms of '(==)'.
