Hello,
It would be really nice to use OverloadedStrings when constructing a
ShowS, for example in a definition of showsPrec in an instance for
Show.
The patch attached in the ticket[3544] adds the necessary instance to
base/GHC/Show.lhs:
instance IsString ShowS where
   fromString = showString
Note that this does require TypeSynonymInstances.
Discussion period 2 weeks.

Bas
[3544] http://hackage.haskell.org/trac/ghc/ticket/3544
Just a reminder for this proposal. One week has passed and one to go.

Any comments, +1 or -1?

regards,

Bas
