to make reference to template parameters. This is only a partial implementation; we retain the restriction that the argument must not be type-dependent, since it's unclear how that would work given the existence of other language rules requiring an exact type match in this context, even for type-dependent cases (a question has been raised on the core reflector). llvm-svn: 290647
