--- Comment #2 from Matthias Kretz <kretz at kde dot org> 2012-05-25 08:53:36 UTC --- Does the standard allow exceptions in constexpr? A throw is not exactly a return statement, but according to the rule "constexpr function shall satisfy [...] exactly one return statement" I'd expect a constexpr function can never throw anyway. Thus the noexcept itself seems to make no sense in the first place.
