--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
See PR 77711 comment 1 where I said:

The same applies here. The expression 'v.size' (when not followed by
parentheses) is not valid C++. Instead of trying to resolve which operator<<
can be used for a nonsense expression we should just give an error immediately
after parsing v.size, which is what Clang does:
50462.cc:10:18: error: reference to non-static member function must be called;
did you mean to call it with no arguments?
{ std::cout << v.size; }
~~^~~~
()
50462.cc:5:6: note: possible target for call
int size() {};
^
50462.cc:6:6: note: possible target for call
int size() const {};
^
1 error generated.
