--- Comment #1 from Simen Kjaeraas <simen.kjaras at gmail.com> ---
Reduced:

unittest {
    enum A;
    enum E { @A a }

    pragma(msg, getAllUDAs!(E.a));
}

alias getAllUDAs(A...) = __traits(getAttributes, A);

By introducting a symbol A at module scope we can even have getAllUDAs return
the wrong thing. Obviously it's looking up things in the wrong scope.
