I'm fairly sure that's not valid.
That relies on an implicit conversion to bool, not a contextual conversion to
bool, and 18.8.5 also says "exception_ptr shall not be implicitly convertible
to any arithmetic, enumeration, or pointer type."
This should work though:
if (bool(e))
I'll fix that and add tests to check implicit conversions don't work (I think
that requirement is also new since exception_ptr was last worked on.)
