I'm just kind of aghast at the idea of "teaching" anyone how to
program games by using large, imperative chunks of code. I don't see
functions as being a "fairly large concept" at all, and utterly vital
to being able to write anything but the most basic 'hello world'
example code.

Wouldn't it be better to teach people the basics of coding -before-
setting out to optimise their code?
