No, it's not. It's nothing like that proposal. Just look at the
proposal's abstract, and you'll see that what it provides has nothing
to do with P0847. That proposal is about allowing you to use member
call syntax to call non-member functions. This proposal has nothing to
do with function calls themselves.
This proposal is about how you *write* a member function, not how you call one.
