in reply to OT: How to find anagrams?

isn't this one of those problems which turns into an n2, n3, n4 type problem, with n as a big number to start with?
:-D, most problems end up that way!

I think dragonchild has a good algorithm, I would only add that, before looping you should make a pass over your dictionary and copy to a new file/memory-location all words that are composed only of the letters ACELNS. This way you will be able to conduct consequent searches on this small subset of the whole dictionary as opposed to the whole thing. This will optimize your O() a lot ( btw O means the speed at which each operation is made, don't think about it a lot if you're not familiar with it... )

[Corion]: Hmm. I think overnight I decided on simplifying some code. I have plugin classes that do data import (.csv, .yml, .json) and for that create objects on which then ->load() is called. But YAML::XS doesn't have an object, so I wrote my own wrapper.
[Corion]: This evening, I'll kill that wrapper again, and just call LoadFile() in the plugin class directly instead of creating a go-between object for no real gain.
[Corion]: Writing these import plugins was really nice though - in about 2 hours, I had imports for CSV, YAML and JSON, and adding XLS(X), SQLite (or DBI) data sources is also trivial. I'm idly wondering about separating the plugin into transport+parser, so ...
[Corion]: ... http:// URLs could be retrieved and then parsed, but I think that that would be overkill for a toy static site generator ;)
