Right, using the notify function would only apply in the case of
removal and deletion of populations from the colonyList.  In any case,
my point is that access and mutation of colonyList can be localized.
If you do this, if you organize things such that an expected mutation
of colonyList sets a flag, the access method can do the right thing to
adapt (e.g. recreating the index).  Just one general approach.

Yes.  (References are actually stored in a list in the object that is
set up to do the notification.)
