I thought yesterday that every thing was clear. But I have
a doubt now with the following line:

> >>> g = f.__get__(17, None)

The signature of  __get__ method is  __get__ (self, inst, owner)  so
once again the first parameter is filled automatically.
Is method __get__ itself a descriptor with an attribute __get__ to perform
the operation ? Hum, it would be endless ...

vars(f.__get__)
TypeError: vars() argument must have __dict__ attribute

no, so how does it work here ?
