Isn't this going to create a brand new instance attribute x.foo that
has nothing to do with the descriptor anyway?
No, it's up to the descriptor __set__ method what happens in this case.
Think of the standard 'property' descriptor, the fset function can do
whatever it wants.
If it gets called, that is.
Also, a data descriptor takes precedence over any instance attribute of
the same name that might exist.
This was the bit I wasn't clear on. Thanks!
