this is probably drifting a bit far from the original question, but i have
used function scope to hide information "global" to a few functions.  the
idea is to use a factory function that generates them all.

  def factory():

    a = 12
    b = 34

    def ifamultb(x):
      if a == x:
        return x * b
      else:
        return x

    def somethinelse(x):
      blah blah

  (ifamultb, somethinelse) = factory()

that's off the top of my head.  you might need to work around python's
stupid scoping rules with hidden params:

    def ifamultb(x, a=a):

etc
