if what you mean by 'importer' is the one that really cause py to load
the mod, then why not dynamically set it?

foo.py
------
import bar, sys
if '_importer' not in bar.__dict__: bar._importer =
sys.modules[__name__]

bar.py
------
def show_importer(): return _importer

or

you could borrow space from builtins. i don't know if it breaks any
rule ;)

foo.py
------
def set_importer(mod):
    bdict = (__builtins__.__dict__ if __name__ == '__main__' else
__builtins__)
    if '_importer' not in bdict:
            bdict['_importer'] = {mod : sys.modules[__name__]}
    else:
        if mod not in bdict:
            bdict['_importer'][mod] = sys.modules[__name__]

import bar
set_importer(bar)
