DMD 0.137 output:
    test.d(9): this for stuff needs to be type Foo not type Bar


Was this intended? If so, what is the reason? Shouldn't the type  
implicitly convert to its base to find the member?

I must admit that this looks odd ...

struct Foo
{
    void stuff() { }
}
typedef Foo Bar;
int main()
{
    Bar b;
    (cast(Foo)b).stuff(); // now it works.
    return 0;
}


Also, instead of typedef, alias makes it compile, but I guess that's not
your point.
