In this case the punctuation is there thanks to grammatical descriptivists. It's there to imitate speech. No, you don't need to put a comma there, but someone has because when it was said out loud, there was a pause at that position. Now why was there a pause? Because the sentence should read: "The return value is ignored. Why? Because we want to continue etc etc" it's basically grammar as a study versus grammar in common use.

Prescriptivists wouldn't use a comma there, descriptivists would. You get to pick which one you agree with.

I obviously have some googling to do.

Although as a mathematician and engineer, i suspect i would lean more towards prescriptivism. Then again, as someone who knows fuck all about natural linguistics, descriptivism seems to be what's spontaneously accessible.

No, it just bugs me when i don't understand things.
Why do you think it's a waste of time?
