Guido did some work on this (as xreload) for Py3K, but gave up for the moment.
In the meantime, you can sometimes get a bit closer with indirection.
from othermod import anobject # won't notice if anobject is replaced later
othermod.anobject # always looks up the current anobject
That said, subclasses and existing instances generally don't use
indirection, because it is slower; replacing bound methods will almost
certainly always require at least the moral equivalanent of reloading
the dialog after reloading the module.
