loop over all parameters of all overloads of all members

[Frustrated]

The following code craps out on the inner for each

                foreach (am; __traits(derivedMembers, B))
                        foreach (m; [__traits(getOverloads, B, am)])
                        {

                        }

So how can I loop over all the parameters of all the overloads of
all the members of a class?

Create some weird mapping tuple?

I guess we are not going to get a static foreach any time soon?
