--- Comment #2 from Jonathan M Davis <issues.dlang at jmdavisProg.com> ---
This just came up in the learn newsgroup again:

---
struct bar {
     public alias pubInt = int;
     private alias privInt = int;
}

static foreach(member ; __traits(allMembers, bar)) {
     // Error: argument `int` has no visibility
     pragma(msg, __traits(getVisibility, __traits(getMember, bar, member)));
}
---

I would guess that the core problem here is that the alias gets replaced with
what it's an alias to before getVisibility actually operates on it, which is
obviously the wrong order to do things in.
