Description
This problem is similar to #6273 as recently added by @jwakely
The expected to be voted in paper P0792R14 suggests to
add the declaration
template<class... S> class function_ref; // not defined
to [func.wrap.ref.class]. This declaration is redundant since the paper suggests already to add the same declaration to [functional.syn], so this should not be done. Or, if the original paper needs to be applied as suggested, this declaration should be removed afterwards through this issue here.

Research direction
Compare the declaration proposed in P0792R14 with the declarations in [func.wrap.ref.class] and [functional.syn]. Confirm that the same function_ref primary-template declaration already appears in [functional.syn], then ensure the redundant declaration is not retained in [func.wrap.ref.class].
