    Perhaps I'm misunderstanding what you're saying, but given is a topicalizer, aliasing a lexically scoped $_ to a scalar's value which when operates on. The if/elsif construct doesn't create topics. Given this difference in functionality, how is given/when syntactic sugar for if/elsif?

[Corion]: choroba: Currently two or three that my program handles (WWW::Mechanize:: Chrome), but there might be more that become interesting
[Corion]: But I don't expect more than 100 to be active at the same time, so I'm not really sure if there is a not-too-fancy data structure that is maintained with few lines of code where the performance is better than the linear scan ;)
[Corion]: But I should do a mock-up program so that others can see what I'm talking about ;)
[robby_dobby]: Corion: I hope you know all too well that passing around "fancy" datastructures is a recipe for disaster :-)
[robby_dobby]: As in, it's-too-fancy- that-it-will-be- messy-to-handle
[choroba]: bit vectors as keys?
[robby_dobby]: Hmm, I keep falling asleep at my desk, while maintaining an active appearance. Am I getting old?
[robby_dobby]: Every time I fall asleep, there's a small guy in the dreams, shouting "Whoo!" and it jolts me awake. :/
[Lady_Aleena]: robby_dobby, at least you aren't driving. I seem to always be driving somewhere in my dreams and end up at a weird house.
