I reached a similar conclusion as well, regarding the approach, though I've
specifically avoided "peeking" at the submitted code.
I've yet to write a line of code, as I'm looking at writing a simulator
which will "run" the code and keep track of resources used at the same time.
This requires changing existing code, and, at least in my case, changing
working code means more or less the same thing as starting over, since I've
not looked at the good code for a long time.
