TOS is a tuple of keyword attribute names, TOS1 is the class being matched
against, and TOS2 is the match subject. *count* is the number of positional
sub-patterns.
Pop TOS. If TOS2 is an instance of TOS1 and has the positional and keyword
attributes required by *count* and TOS, set TOS to ``True`` and TOS1 to a
tuple of extracted attributes. Otherwise, set TOS to ``False``.
