We currently need to write different invoke syntax for each of:
regular function call, functor or a member function (through std::invoke)
invoke on a fn::pack
transform_to on fn::sum (plus return type calculation for the same effect as transform)
Ideally this should be pulled into different overloads of fn::invoke (and corresponding specializations of fn::invocable and fn::invocable_r), which will enable us to simplify lots of things (e.g. implementation of fn::optional , fn::expected and many|all the functors).
Eventually we will propose to add this functionality into std::invoke (and family)
