--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I believe this is the correct behaviour.
https://wg21.link/lwg3065 changed operator/ to be a hidden friend, which means
it can only be found by ADL when at least one argument is a path.
in the expression `dir / "file"` neither argument has type path, so the
operator is not found by ADL. You would need to do:
dir.path() / "file"
or:
static_cast<const path&>(dir) / "file"
However, as https://wg21.link/lwg3171 points out, such changes to path can have
undesirable consequences for directory_entry. I will ask for LWG 3171 to also
consider operator/ and the comparison operators.
