Oh, alright (oops). Simply the widely understood jargon of pure
and impure functions.
Bitten by surprise because my Bison use isn't pure yet. I had
read a bit about the topic, and decided to postpone that as a
to do, and I long had forgot. However from a maintainability
perspective, that looks like a horrendously big mistake towards
my future self, that I should amend as soon as possible.
Thanks,
