I have one question.
In following case, what does foo receive as arg?

void main()
{
    typeof(foo.a) E;
    E a = foo.b;
    foo(a);   // == foo(foo.a) or foo(foo.b) ?
}

I think the enum scope inference from their member name is nearly impossible,
because D has template function.
The feature requires a function signature to determine the argument types, but
template function call requires argument types to determine the function
signature!
