There is already an IsString class, although IIRC it deals solely with  
converting String to/from a member of IsString.  Most of the rest  
involves invoking functions as S.whatever and then importing some  
variant of Data.ByteString or Data.List qualified as S.  (The latter  
is kinda unfortunate, but Data.String was taken to provide the  
IsString class.  Code would look a bit saner if Data.String reexported  
Data.List for this usage model; note that this model only makes sense  
with IsString, so it would be a hopefuly backward compatible addition.)
