I fairly recently gave some perl coaching to a VB programmer who has been dabbling in perl scripts. He had a problem that required some debugging; I introduced him to the delights of perl5db and we found the problem - a typo in a variable name.

I then explained to him about use strict; and he agreed it was a good idea, and should be in any agreed coding standards. I also asked him whether he would conceive of having production VB code without "option explicit". He took my point.
