I looked through your code a bit, and there are a couple of things I'd flag in a code review (e.g. use of non-local variables). Ironically these are things that are a lot harder to do, and easier to spot, if proper modules are used.
I'm sure you would, and if you looked at earlier versions of that same code you'd see mountains more of those.
I'd love for everything to be perfectly pure though and side effect free. The pressure is always on to improve it further. As for code review, feel free and open tickets for whatever you spot and hopefully one day I'll get around to it. Better yet: submit pull requests.
