Subject: Different Ways To Loop

I love the flexibility of Ruby.  It gives you several ways to do
something, leaving you to pick the most appropriate one.  In the
spirit of showing off the flexibility of Ruby, I'd like to see how
many different ways there are to write a loop that prints the numbers
1 to 100, one on each line.  I'll start off:

  1.upto(100) { |x| puts x }

I know there's at least a dozen more ways to do this...
