Re: String != [Char]

Does Python 3 have the equivalent of LANGUAGE pragmas? That is, as a GHC user i can add {-# LANGUAGE OLD_STRINGS -#} and my program works with the new language standard! I think what ruined Perl 6 is that it is still under development! Avoiding breakage is important. But throwing around comparisons to Perl 6 is not going to help move the discussion along!

2012/3/22 Greg Weber : But now we have at least two tasks to do before we can put up the proposal: define what operations should be supported by String and should we apply this proposal in the next batch. Given that this proposal will break many codebases (we shouldn't hope to apply all of list's syntax to this string type) should we apply it alone or wait until we have more other codebase-breakers to apply ?

I very much hope that the Haskell committee will never ever accept a proposal that "will break many codebases"! That's what ruined Perl 6 und Python 3, and quite unnecessarily so.

Even if I a future Haskell standard defines String as something that doesn't have to be implemented as a list of Char, it still would have to behave as if it was [Char] for most practical purposes (except performance-wise, of course!). That's necessary for compatibility. Or String could just be complemented with an additional standardized Text type, as Greg suggested.
