As Arthur wrote, you probably do not want to have [[maybe_unused]] active for SOME_PLATFORM, too.

Of course you could also #ifdef the maybe_unused attribute in this specific example as an alternative solution, which arguably would not make it more readable.

I don't get it -- why having `foo_other_platform` at all?
[[maybe_unused]] is already doing the right thing, just put it on
`foo`'s arguments?
