Re: De-chunkifying Sequences in Clojure
#2Is there any way to de-chunkify sequences in an exponential way ("uncover" twice as many elements each time instead of a constant number)? Would this be useful?

#3wouldn't it be better to have the intuitive behaviour by default, and the space-optimised behaviour as a configurable option?

The chunking behaviour is transparent unless you have a side-effect in your sequence function, which isn't sensible anyway. The chunked behaviour performs significantly better for the majority of cases which is why it's on by default, I believe.

He also discusses chunked sequences in a video here (near the bottom of the list, the sound is pretty bad):

>transparent unless you have a side-effect
Only if you believe the side effect of using the CPU doesn't count.

yes, i understand the technical tradeoff.
my point is that telling your users they aren't sensible quickly becomes tedious (and tends to annoy them).
