Adding objects to __builtins__

[Matteo Merli]

Hi,
is there a way to save objects in the __builtins__ namespace?
the goal is to make them available in all the modules of my app, without
reimporting all the things and keep references...

The curious thing is that when i try from the interactive interpreter the
thing just works:

def a(): .... print "ciao"
.... a() ciao __builtins__.b = a
b() ciao

But i've tried inside a script, recalling objects from other imported
modules, they cannot see them.
Does exist a way to do this, or is just a stupid thing?

Thank you
matteo merli

Does this help?

import __builtins__ Traceback (most recent call last):
File "<stdin>", line 1, in ?
ImportError: No module named __builtins__ import __builtin__

By the way, you *really* shouldn't use this as a "convenient"
way of getting global variables or other things around to your
various modules. That would be almost the worst thing for
code maintainability that you could do. You'll come to hate
yourself for doing it, down the road.

There are some valid use cases for doing such a thing, but
sticking just any old function in there is not it.
