delegation pattern via descriptor

[kedra marbun]

if we limit our discussion to py:
why __{get|set|delete}__ don't receive the 'name' & 'class' from
__{getattribute|{set|del}attr}__
'name' is the name that is searched
'class' is the class whose __dict__ has 'name' bound to descriptor

delegator & delegator are terms from delegation pattern (oop) which is
a specialized  area of IoC
delegate refers to helper obj, which is descriptor obj in the case of
descriptor
delegator is the obj that delegates task to helper obj
