People keep asking and I keep promising to get a lazy loader into Python 3.4. This issue is for me to track what I have done towards meeting that promise.To start, I have something working athttps://code.google.com/p/importers/, but I need to make sure that the code copies any newly assigned objects post-import but before completing an attribute read::  import lazy_mod  lazy_mod.attr = True  # Does not have to trigger import, although there is nothing wrong if it did.  lazy_mod.func()  # Since it might depend on 'attr', don't return attr until after import and 'attr' with a value of True has been set.Also need to see if anything can be done about isinstance/issubclass checks as super() is used for assigning to __loader__ and thus might break checks for ABCs. Maybe create a class from scratch w/o the mixin somehow (which I don't see from looking athttp://docs.python.org/3.4/library/types.html#module-types w/o re-initializing everything)? Somehow get __subclasscheck__() on the super() class? Some other crazy solution that avoids having to call __init__() a second time?
