:-) No problem.
See above. Untested code! Actually pseudo-code. I was just
translating how python would do it. And your method *is*
more rebol-esque (IMHO)

And I find that seeing how different languages handle things
helps *me* alot. I wrote a 'first function for python that -
is more verbose than referencing by index but more clear...
especially when going from a language that references an
initial element as '1' to one that references an initial
element as '0'.
Permission to use your example?
