[ 2022-01-30; Reflector poll ]

Set priority to 3 after reflector poll. Would be resolved by P1642 for C++23, but it's still a defect in C++20.

The <coroutine> header is required for freestanding implementations, but it defines a specialization of std::hash, which is not required for freestanding implementations.

Presumably we should make the std::hash specialization conditionally present.
