Hey Merlyn, I'm with you.
Over 30 years of coding has taught me that no mater how much I thought I knew at any given pojnt in my existence, I can pretty soon prove it wasn't much!
In fact I find it very difficult to revisit code. Usually because I will see so manythings that I would do differently now. Especially with Perl as the size of the toolbox gets bigger and bigger by the week! I have done some things that I am instantly proud of, especially when they get accolades from the client. But self-disenchantment soon sets in and eventually I will only look at it if I am paid to or badgered sufficiently that looking is the only way to peace.
