           Summary: Forward reference with auto return

           Version: D2
          Hardware: All
                OS: All

The compiler should be able to resolve the return type:

struct Tree {
    Tree* left;
}

auto fmap() {
    return new Tree(fmap());
}

void main()
{
    fmap();
}

Error: forward reference to inferred return type of function call 'fmap()'
