Need Help??

So,...you said:

...if you had lazy lists (coming in perl6)...

And I couldn't see how lazy lists would benefit this problem; hence my original question (way back up there^^^ somewhere).

Examine what is said, not who speaks.

Silence betokens consent.

Love the truth but pardon error.

Ahh. I think Re^5: Better mousetrap (getting top N values from list X) is the answer you're looking for. (Or at least a starting place.) -- All code is 100% tested and functional unless otherwise noted.	[reply]

You're correct, `sort` is strict on its input arguments (i.e. it has to evaluate each one), but the importance of laziness comes about because the output is a lazy list. -- All code is 100% tested and functional unless otherwise noted.	[reply] [d/l]
