Overloads

[Márcio Martins via Digitalmars-d-learn]

Consider this snippet:

struct X {
  int foo(Args...)(Args args) if (Args.length > 1) { return 
Args.length; }

  int foo() { return 0; }

  int foo(int y) { return 1; }

  alias Name = string;

  int field_;
}


void listMembers(T)(ref T x) {
  foreach (Member; __traits(derivedMembers, T)) {
    pragma(msg, Member, " ", __traits(getOverloads, x, 
Member).length);
    //pragma(msg, __traits(getProtection, __traits(getMember, x, 
Member))); // Error: argument string has no protection
  }
}

void main() {
  X x;
  listMembers(x);
  //auto fptr = &x.foo; // Error: x.foo(Args...)(Args args) if 
(Args.length > 0) is not an lvalue
}

Output:
foo 0LU
Name 0LU
field_ 0LU
foo 0LU
Name 0LU
field_ 0LU


There seems to be a few problems here:
1. It seems like getOverloads is returning 0 for 'foo' - is this 
a bug? Was expecting a 3 or at least a 2 if the template would be 
ignored.
2. That alias breaks getProtection - is this bug? Seems like it 
should be public.

These two make it quite hard to iterate over and collect info 
about arbitrary aggregates.

I want to get a list of all *public* members, including pointers 
to all public member functions and their overloads, excluding 
template member functions. This is turning out to be hard due to 
these "unexpected behaviors".

Is there anything else I can do?
