This provides a cleaner callstack as a std::function object is never created.

The problem is you throw away type safety. Concepts should be used to get sensible compiler error output. I have no idea what concepts to use here.

That could be addressed by adding a REQUIRES but we are not doing that in other places. I might take a look at this later.
