Actually, I'm not sure which one came first because I rarely use ties and I don't think I've ever used a tied array, so I can't remember when they were introduced to Perl, and I never knowingly use a design pattern. At a guess, I'd say that the pattern was probably a little earlier, but had little if anything to do with tied arrays. Which got me to wondering. How much do really good programmers use design patterns? Use them as in thinking "I have problem A, I can use disign pattern B to solve it", rather than writing code which conforms to a pattern without explicitly aiming to do so. For that matter, how much do people who espouse patterns conciously use them? Maybe expert, or even good programmers are not the target audience. And how many people have actually read that book all the way through? And of those, how many can remember the names of half the patterns? And anyway, in my day "pattern" was spelt "recipe" :-) Hmmm. I wonder what brought all that on? -- Paul Johnson - [EMAIL PROTECTED] http://www.pjcj.net
