use of __new__ to permit "dynamic" completion within (any?) IDE ?

[gst]

Hi,

I met a situation where I was passing an object created in/with an
upper level module class to a lower level module class' instance in
one of its __init__ argument and saving a ref of the upper object in
that lower level class' new instance.

But in my IDE I want the completion to also work from within the lower
level module when it's refering to the object passed from the upper
level:


Well, I'm sure I'm not very clear in my terms (and probably a bit long
in the sentence) so here it is in code:


files:
module1.py
subpackage/module2.py


file module1.py:

from subpackage.module2 import class2

class class1(object):

    def __new__(cls, _self=None, *args, **kwargs):
        if _self:  ## we've been passed an instance already
initialyzed
                     ## so directly return it instead of creating a
new object.
            return _self
        return object.__new__(cls)

    def __init__(self, _self=None, *args, **kwargs):
        if _self:  ## we've been passed an instance already
initialyzed
                     ## so directly returns
            ## assert(self is _self) ?
            return
        self.object2 = class2(object1=self, "blip", "blop")
        # others init


file module2.py:

class class2(object):

    def __init__(self, object1, *args, **kwargs):

        from ..module1 import class1

        self.object1 = class1(_self=object1)    ## instead of:
self.object1 = object1

    ## others functions and/or init..
    ## where  now I've completion working on self.object1 :
    ## if I add(or remove) fields/methods in module1 (and save) then
    ## I have them available(or disappeared) in the completion when
executed from this submodule.
    ## This ofcourse permits to save me of remembering all of the
class1 attributes/methods when I'm working with self.object1 from
within one of class2 methods.


What do you think of this ?

I guess there can be others ways of doing this..  ?

Thanks,

note: I'm using Eclipse 3.5.2 with pydev so (I don't really know how
others IDE can handle this case) .
