I'm afraid I don't know what you're driving at with those examples.
It is a single example. It shows that when UCFS and the lack of operator
-> try to play together, the result is no longer as simple and elegant
as one tries to sell them. It was given as a response to Andrei's
request for examples of cross-features interference causing complexity.
I assumed you were talking about UB or unsafe behavior. Thanks for the
clarification.
As to the specific case here, the spec doesn't say "vice versa":
"A free function can be called with a syntax that looks as if the
function were a member function of its first parameter type."

Not the other way.
