I have heard that RDP is prominent in production parsers, I wonder is it true? And is it pure handwritten RDP or combined with other automated techniques?
One reason hand-written recursive-descent parsers are common is because a lot of languages are poorly designed, and it's easier to hack around the mistakes in a hand-written parser.
For new languages this should be avoided - just design a sane grammar in the first place.
