And other thing.... One of the reasons that many people use Java and Perl is not so much for writing giant programs as for the fact that many giant programs have in great part (in effect) _already_ been written in Java and Perl for them. These things are of course the extensive set of standard and optional extension libraries. It is Java and Perl's OO features (as troublesome as they are for novices) that made this mountainous infrastructure tolerably easy for experts to implement--but much more importantly--make it very easy to for users to exploit. This is one reason why you really want an OO language for even many fairly simple tasks. The great majority of Perl programmers never use OO directly, but almost all Perl4 programmers switched to Perl5 (among other reasons) in order to _indirectly_ take advantage of Perl5's OO features (and of course users that started out with Perl5 also do the same thing). Moreover, by using an OO language for simple stuff, you don't have to change languages for more sophisticated tasks, which relates to other points that others have previously made. This spurious and counterproductive scripting issue is another reason that I think it is exceedingly foolish to characterize languages in terms of their implementation. Since people just seem to have to have some superfluous adjectives to stereotypically pigeonhole programming languages, then I think it is much more appropriate to call languages like Perl, Python, and Ruby "very high level languages" (with Ruby being the highest level language in the series). Please pardon my end of the week humor (pun intended).... OK Ruby marketeers, let's hear you all say in unison, "Ruby is a very high level language." What did you say? "Ruby is a very high level language". What's that again? "Ruby is a very high level language." Once more more with feeling! "RUBY IS A VERY HIGH LEVEL LANGUAGE." Once more like you really mean it! "RUBY IS A VERY HIGH LEVEL LANGUAGE ! ! ! !" Great! You got it! 8-) Conrad
