Possibly support N4381-style function objects?

See [N4381](https://wg21.link/N4381). These are global function objects that should be documented like functions, rather than objects. They are used extensively in range-v3.

https://github.com/Eelis/draft/commit/14268b09fbeecde9f059984ed66aef08941d652f uses `\oldconceptref` but I don't think the code to handle that has been pushed here.
