Thank you, I have not read the Ruby User Guide (maybe I should now that 
I know it documents some interesting details of Ruby?) and I'm pleased 
about this behavior indeed being by purpose. It might be too slow for 
completely replacing the built-in while with it, but there might well be 
some interesting things it can still be used for.

I keep being amazed at how much hidden power there is in Ruby while it 
still remains so simple. matz really spent lots of thought about 
carefully selecting only the best features.
