Currently narrowing conversions are still forbidden in noexcept and explicit
specifiers.

The inconsistency is acknowledged in C++23 (WG21-P1401R5), but it seems that
P1401 is not a DR, as the related CWG 2320 is closed as extension. I don't =
know
whether we should reject narrowing conversions in static_assert/if constexp=
r in
earlier modes.=
