I just tried out (0..9).cycle {|n| puts n} in an irb session and had to 
Ctrl+C it to stop the loop. However when wrapped in a Enumerator like 
your example above, just an Enumerator::Generator object is returned. 
What happens to the infinite loop - does it still crunch the numbers out 
in the background or does it "stop" at some point? I looked at puts 
e.methods.sort
but they aren't very revealing of what's going on with the loop...
