Hi
In "Factor Philosophy", slava writes: "Imperative programming and indexed
loops are almost always not the most idiomatic solution."
I've implemented this puzzle (
http://mindyourdecisions.com/blog/2013/04/22/100-light-bulbs-puzzle/ )
using a side-effecting function: http://paste.factorcode.org/paste?id=2914
The words do-switching and toggle-switches implement the equivalent of a
nested loop.
Without using recursion, counted for loops or side-effecting functions,
what is an idiomatic way of implementing this nested iteration?
