Description
It appears that the overload resolution logic that attempts a second pass with convert=true does not properly handle keyword-only arguments:
The check there only considers positional arguments. So if you only have keyword-only arguments, a second pass is not attempted.
Is there some reason for that behavior, or should it be changed to also consider keyword arguments?
