I understand. I like consistency, too. And I guess at this point
consistency is more important than the minor inconveniences that
cause "repeat" starting at 1. I was just curious about your reasons.

I use LogoFE's "iota" :)

show iota 10
[0 1 2 3 4 5 6 7 8 9]

and do things like:

cs foreach iota 10 [setturtle ? rt random 360 fd 100]
