----------------
https://wg21.link/p2548 `copyable_function` is making progress through the committee. We should discuss how these two types are going to interoperate and whether that should inform the representation we choose for `move_only_function`. In particular, it would be a nice QOI property to have `move_only_function(copyable_function&&)` just steal the guts of the `copyable_function` and make no allocation.
