Review comment:
to be clear I don't think this is needed, I just wanted to point it out
-- it took me quite a while to get comfortable with the functional parts of
rust -- at first I thought it was just style preference, but then the longer I
work in rust I realize it is one of the key mechanisms rust uses to eliminate
bounds checks during iteration
