Yes, but if the descriptor object is a class, then there is no "self"
because it's called as a static method. The missing owner parameter is
the only problem when it's called in the way that the descriptor howto
says it is called [type(b).__dict__['x'].__get__(b, type(b))].

It doesn't actually work as written, of course, since it doesn't have
any way of knowing myprop is meant to be a descriptor. But the self
parameter isn't the issue.

Incidentally, I'm not sure I understand what the owner parameter is for,
and what purpose it can be useful for which it isn't also needed on the
setter.
