After thinking about it for a while, I'm positive it would be a LOT of work to get that to work in general, if it is even possible. Even getting it to work in only specific, limited cases (such as within a module) would probably not be easy, since it is such an indirect kind of thing. It probably wouldn't be all that usefull anyway, either.

We must know GB> where to look for "foo" since we know the type of "foo" from its GB> arguments and return value (it passed the type checker after all). because compiler can't determine logic of your program. and your program may use some class methods only for some of types for which this class is defined -- Best regards, Bulat mailto:bulatz@HotPOP.com
