Suppose I have an object containing an array called children. I can
therefore build a tree out of such objects.
I thought it might be useful to have a descendent generator, so I could
write:
for thing in self.genDescendents():
foo(thing)
expecting foo to be called for each descendent

You can try the sched module (import sched).
You give it a time at which to call a callback. Then in the callback you
can reset the "alarm" for a minute later, using enterabs.
