Nah, I didn't miss the point, i just forgot to pass in a
version number to my virtual python "fetch_answer" function --
which defaults to Python2.x
 def fetch_answer(question, pyver=2):
 return database[pyver].get(question, "Urmm???")

PS: Okay! Okay! So I forgot to call list on the range! So
sue me!!! ;-)
