Add instance IsString ShowS where fromString = showString
It would be really nice to use OverloadedStrings when writing a definition of showsPrec in an instance for Show.
The attached patch adds the necessary instance to base/GHC/Show.lhs
:
instance IsString ShowS where
fromString = showString
Note that this does require TypeSynonymInstances
.
