I agree. The argument for (A) would be to try to avoid the (user*/implementation) complexity of (B). Once you have (B) you (probably) don't want (A). > Which I don't understand; seems to me that, in the context of (b), it's a > way to easily provide more information to the type inferencer (which, given > that (b) adds more complexity to the inferencer, looks like a way to control > that complexity in practice) without hardcoding a type. I didn't quite follow this part. * Explaining (A) is easy and can be done in a sentence or two e.g. "In addition to module names, type names can now be used to disambiguate record fields. In case of ambiguity between module names and type names, the module name is preferred and the user needs to prefix the type name with a module name to refer to the type name." _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
