Interesting. I wonder if we're discussing two separate events. The one I
knew of supposedly involved a regex with a misplaced .*, which seems like
a fairly fundamentally different lesson. Both valuble, though...
(and thus is demonstrated one of the hazards of a purely oral tradition...
human memories are notorious for showing all of the properties of most
complex neural networks, including partial matching triggering more than
one pattern...)
