Maybe according to D specs this is not supposed to work, but is this good to
support? It's useful as inner types are becoming more and more common in D
code:


struct Tree1 {
    static struct Node { int x; }
}
struct Tree2 {
    static struct Node { int x, y; }
}
void foo(T)(T.Node n1, T.Node n2) {} // ***
void main() {
    Tree1.Node n1, n2;
    foo(n1, n2);
}



DMD 2.061alpha gives:

temp.d(10): Error: undefined identifier T.Node
temp.d(10): Error: template temp.foo does not match any function template
declaration
temp.d(10): Error: template temp.foo(T) cannot deduce template function from
argument types !()(Node,Node)
