Thanks for a very well crafted technical insight into Perl's smarts!

As a newbie this gave me an idea on what it is Perl does "behind the scenes" for its users.

Even more interestingly it gives and example the process of research, review and repair working in the Open Source arena. I can use this to show others and calm their "but who supports it?" fears.

Thanks again for taking the time to post.

robin++ of course.
