Thats still doesn't answer the question. It defends why its a good
idea to count from 1. But an actual answer is purely historical. Maybe
you want to change question, so an answer that justifies Arrays-from-1
fits? (I personally don't care so much, as mentally somewhat flexible
person you can adept).

Yes, but isn't a FAQ about questions that are frequently asked
compared to questions that we think should be asked instead? People
are asking for continue and other control structures like redo etc.

We're not Wikipedia :-)
