Re^2: exists *{$glob} ? (+)

That leaves a couple of questions:

If you were writing the program over, would you use the same strategy of thousands of classes, or might you switch to a more conventional scheme?
Can you imagine writing a program that would use more than 8000 classes and need more than 500k instances of any single class active concurrently?

As I didn't have a database I could use, then I would definitely use that scheme. Ideally, I would've stored everything in a database. 8k classes? Yes, in the kind of situation I described earlier. 500k instances? Uhhh ... assuming you used 1k of RAM per instance, which is a lowball estimate, you would need 500M of RAM, just for those objects. If you're doing something that resource-intensive, you probably need it to actually complete running before the Sun dies. So, you're probably not writing it in Perl. Either that or you should've use a database. ------ We are the carpenters and bricklayers of the Information Age.
