I'm staring at your post in disbelief. You're not clear on the question:

How does chomp change the contents of the string without the need to pass it in by reference?

To me that's a perfectly simple and lucid question, with a good code example. To imply that it's unclear is simply disingenuous and somewhat demeaning. Maybe the concept wasn't clear to you, but I don't think that's the fault of the OP.
