Getting the name of an assignment

[Adam Atlas]

Is it possible for an object, in its __init__ method, to find out if it
is being assigned to a variable, and if so, what that variable's name
is? I can think of some potentially ugly ways of finding out using
sys._getframe, but if possible I'd prefer something less exotic.
(Basically I have a class whose instances, upon being created, need a
'name' property, and if it's being assigned to a variable immediately,
that variable's name would be the best value of 'name'; to make the
code cleaner and less redundant, it would be best if it knew its own
name upon creation, just like functions and classes do, without the
code having to pass it its own name as a string.)
