it works eitherway but the proposed syntax is IMHO better aligned
(when used in a function definition) as it matches better the syntax
from C++ attribute: maybe_unused (since C++17) [1]

__attribute__(unused) (the GCC extension) is meant to be applied to
function declarations, but we are not generating those.
