...which, unlike std::is_signed, also requires that T is an integer type, not just any arithmetic type, but which appears to fit well here anyway. But LLVM 12 libc++, which is apparently used by Android builds, only provides a bare-bones <concepts> that lacks std::signed_integral (among others), so for now introduce o3tl/concepts.hxx providing what's missing (incl. std::integral and std::unsigned_integral, for some kind of consistency).
