Look at that, there's an entire section on internals. Honestly, I didn't even consider looking there, I just assumed it would be all about syntax and never bothered to check. Thanks!

You'll quickly find which parts of the manual are interesting to you and which ones just repeat what you already know (or could have guessed on your own). Since the manual is very well structured, skipping those parts is very easy.
