Naw, if you are going to use list interpolation go all the way and save
yourself all of that ugly indexing into the dict.

Yes, I cede that explicit indexing is faster by quite a bit.
There is a somewhat philosophical decision for why I avoided that. I
prefer to try to present python with as big of a picture of what I want

for-loop describes how to.

iteration.next()'s, you can set an optional parameter to a smaller
