--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Jason, is this resolution definitely correct? Clang and EDG agree with GCC 4.6
here, and [over.best.ics] does seem relevant.
Maybe related, maybe not. G++ also rejects:
struct A {
explicit operator bool() const { return false; }
};
A a;
bool b = bool{a};
which Clang and EDG accept, and it certainly seems odd when bool(a) and (bool)a
are OK.
