I think that using [[maybe_unused]] is better than disabling the warning
because it more explicitly indicates that it being unused is not a mistake
and the programmer was aware of it.

One warning, or was it actually an error, that does annoy me quite a bit
is the "narrowing conversion" thingie. I think it was introduced in C++11
or newer, and was never a problem before. To this day I'm not sure why
that warning/error is necessary.

(Maybe it has something to do with uniform initialization, which turned
out to be quite a mess?)
