# can arbitrary imperative code be chopped up into a loop with a functional step?

# "comm" indicates some communication to an external computer or otherwise side-effecty step
# order of them presumably matters 
# code is made up. It's an arbitrary collection of steps and "if" statements
# BUT! it's very similar to actual code I found at the office. :) #java

# Note: I think the following transformation is harder in typed langs. 
# I wish not to deal with that at the moment. Will accept any chance no matter how verbose or clunky.
