I hadn't noticed. I sort of assumed that it was getting added along with
all the algorithms constexpr-fied for C++20 in Albuquerque. According to
cppreference, it's been constexpr since C++14.
Anyway, I can't get the compiler to treat the result of get_arity as a
constant expression using std::max, even in C++17 mode with a recent-ish
Clang, so I'm leaving the example as-is for now.
