Hi Dan, That is a very good question. It is quite possible to write Perl in a clear, readable manner. For all the fun the guys are having with the concept, it really akes sense only with a single statement, or a set of statements that is very tightly bound logically. A good test for whether using this construct is appropriate is to speak the code aloud, and see if it sounds crisp--like "Do the dishes if they're dirty."
