Re: Example how to count in N3

Hi Patrick

Try list:iterate <http://eulersharp.sourceforge.net/2003/03swap/eye-builtins.html>. See http://ppr.cs.dal.ca:3002/n3/editor/s/2rJmxYti <http://ppr.cs.dal.ca:3002/n3/editor/s/2rJmxYti> for an example.

(This is a new builtin introduced by the community group and supported by eye and jen3.)
