Of course only an experiment can say either way.
I think his point is that if I'm using three libraries, each of which uses a different String type, that's a lot of boundaries. Perhaps worse yet, if I'm a library author and I want to be a good citizen, I have to write three versions of my code (or create my own StringLike typeclass). I know of an example off-hand: http://nominolo.blogspot.com/2007/05/networkhttp-bytestrings.html (Of course, as I read that, I see that the lazy code is different from the strict code, but I'll just ignore that for the sake of, uh, argument.) (Sorry if this is a dupe; long thread, and I have to go to work.) _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
