There is a ListLike package, which does this nice abstraction. but I don't know if it is ready for and/or enough complete for serious usage. I´m thinking into using it for the same reasons.
Anyone has some experiences to share about it?
I've used it in the past and it's solid, it's been around for a while and the original author knows his Haskell. Things I don't like: * The classes are huge: http://hackage.haskell.org/packages/archive/ListLike/3.1.6/doc/html/Data-Lis.... I'd much rater prefer to have all those utilities functions outside the type class, for no particular reason other then the ugliness of the type class. * It defines its own wrappers for `ByteString': http://hackage.haskell.org/packages/archive/ListLike/3.1.6/doc/html/Data-Lis.... * It doesn't have instances for `Text', you have to resort to the `listlike-instances' package. In any case I think it's on the right track, I'd really like something like that, but much simpler, to be in `base'. Francesco
