Hey,

In the process of running one of my script on IronRuby I needed upto,  
so here it is, along with his downto friend.

I was wondering if I could simply call Step with the relevant limit  
and step from upto/downto, but wasn’t sure that was correct.

I’ve basically monkey saw, monkey did the whole thing, please correct  
me if I got some parts wrong.

Looks good. I think you’re right about Step though. I’ll try replacing  
the methods with direct calls to Step and see if it works.
