( #3333=superdoc: print w/replies, xml ) Need Help??
Until I recently saw a reference to this discussion thread in a CPAN review of List::Compare, I was unaware that my module was being discussed in the Monastery. So today I'd like to share some thoughts on the issues raised. As these issues were raised by various monks, I'll reply to the individual threads today but try to integrate these comments in the talk I am giving on List::Compare at YAPC::NA in Buffalo two weeks from today.

Re: Dragonchild on List::Compare not working with references:

The real-world production problems for which I originally developed List::Compare did not include lists of Perl references. The module was not designed to handle them and has never been tested against them.

If you can suggest a way for the module to detect when a list passed to the constructor (or a function in List::Compare::Functional) contains a reference, I will be happy to generate a 'die' at that point. Otherwise, I'll simply include a warning against this in the next revision of the documentation.

Re: Dragonchild on List::Compare not preserving order

I don't see any particular reason why a report on the the intersection, union, etc., of two or more lists should come back in any particular order. Whatever order the original lists had is untouched; the order of the set comparisons is irrelevant. As the documentation says at a couple of points, List::Compare was designed to answer the question: Was this item seen in that list? Pure and simple. In what position in the list the item was seen is a question for a different module to answer. Jim Keenan
