I don't know what to say other than I am pretty sure I have never encountered it before. I have been coding for over 30 years, 20 years professionally, and have never seen it. You can see by my account age and comment history that I have been active on HN for 15 years.
I actually have interest in game programming, too. So I don't know.
I am sure I'll encounter it 10 times this week now, good old Baeder-Meinhoff
