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.

regards,

Bas

Just a reminder for this proposal. One week has passed and one to go.

Any comments, +1 or -1?
