Research direction

Start with the [func.wrap.ref] class wording linked in the issue and review the surrounding declaration and comment thread for the naming conventions being applied. The work is done when the template parameter in the constant_wrapper<c, F> declaration has an agreed replacement name and the draft wording reflects it.

Written by the indexing model from the issue text.

Description

P3-Other

https://eel.is/c++draft/func.wrap.ref#class:

template<auto c, class F> constexpr function_ref(constant_wrapper<c, F>) noexcept;

The use of a lowercase c as the template parameter name here seems a bit odd to me; in libraries, we rarely seem to use a single lowercase letter as a template parameter. The c here also overlaps with the c in cv.

Would it be better to use X, or even _ (because we didn't use it at all)?
