I also tried to add a warning like EDG's (see the PR) but it gave a
false positive for direct-list-init of scoped enums (P0138R2, r240449)
because that code goes through build_c_cast to perform the conversion,
so looks like a cast to my new warning.
The enum init code could strip the cv-quals when calling build_c_cast
to avoid the warning.
Thanks, that works. I don't think this warning fits under any existing
option, so I'll add a new one. -Wuseless-cast-qual maybe? Or is that
too close to -Wuseless-cast and -Wcast-qual and would cause confusion?
