Here, I'm using mixin template fooImpl to create a finite set of non-template functions. In particular, I'm generating the functions "foo(int)" and "foo(long)".

Yet, when making the call to "foo" with an int, the compiler complains of finding multiple matches, failing to "see" that there is an exact match.

Apparently, I think the compiler sees "foo" as template functions "fooImpl!long.foo(long)", so they all equally match. I think this is wrong behavior.

The specs state that "If two different mixins are put in the same scope, and each define a declaration with the same name, there is an ambiguity error when the declaration is referenced", however this is clearly not the case, since "foo(s)" is correctly resolved. foo(int) and foo(long) should also correctly resolve just as well.
