I agree 100%. Well maybe 99%.

I'm sure most of of us remember being taught "we can use any delimiters for regex......but don't."
My first question was always "Why??" and this serves as a great example of why. It serves to show that unless you understand what you are doing you may get unexpected results that you will also not understand.

So I agree that it's not good to show how not to do it, but it is sometimes helpful to show why you should not be surprised by some of the results you may find when you step outside of the saftey of more "standard" coding techniques.
My 2 cents worth anyway.
