Re: What is the purpose of static typing?

The object can always use introspection to choose the right method though

Well, it *would* be possible, but it would mean that the call pattern would have to be *extremely* dynamically compiled, and I am afraid that not even G5 would offer muscle enough for *that*.

Theories apart, the fact is that GCC does not compile calling by such a dynamic way -- and in near future absolutely won't. In farther future, who knows? It would be very nice, but the efficiency penalty would be vast.

That said, static types are indeed almost superfluous from the functionality point of view. The only situation when they can't be replaced by ids without any problems are -- slightly incorrect, but possible -- messages with same name, but different signatures, like

@interface Foo
-(int)blah;
@end
@interface Bar
-(double)blah;
@end

Now, [(Foo*)x blah] and [(Bar*)x blah] are compiled differently.
