How does the C++17 proposal for uniform call syntax intend to handle namespaces?

Question

As far as I know, there are two propsals for uniform call syntax for C++17 (where the other one is called unified call syntax).

Reading them, I cant see how they intend

Answer 1

Update: C++17 does not get unified call syntax at this time. Motion does not pass. #cpp #cpp17
