--- Comment #24 from Carlos Galvez <carlosgalvezp at gmail dot com> ---
It we want to keep the current behavior, I believe it would be possible to
create  one more trait like "WillEnumBePromotedToSignedInt" that checks exa=
ctly
that, regardless of the underlying type of the enum. See example:

https://godbolt.org/z/38Ev5d1ja

So operator~ would be SFINAE-enabled only if both a) enum is unsigned and b)
enum won't be promoted to signed int.

What do you think?
