As currently proposed (last I checked) this is incorrect.  You have it
backwards.  An instance knows what it is, and a subclass knows who it
inherits from, but the reverse is not true.  For this reason I think
the correct way to spell these should be something like

instance.isinstanceof(class)
class.issubclassof(metaclass)
