I've read a bunch of books on this, but I'm curious what other monks think on the matter.

I'm writing a Collection class. I looked on CPAN, but didn't find anything. My basic design is (tentatively) like this:

• Have a new(), next(), prev(), load(), first(), last()
• Take an array or Collection and create yourself from it.

What do others think? Why isn't there one of these on CPAN? (Or, did I just miss it?)

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
