My first reaction to this was "Since when??!?"
If the only descriptors you're thinking about are things that return callables
from the __get__() method, it makes sense that you've made this mistake.
What needs to be considered though is that not all descriptors provide
callable results. Remember that "property" is a descriptor type; instances
of property are not normally callable.
