Hi, I believe I've heard claims that nothing stops Clojure 1.3 code to be made very close to Java in terms of execution speed. However when trying to match the speed of ad-hoc Heapsort implementation I have faced essential obstacles. Setting type hints and coercions was quite easy. A bit harder

It might be straightforward to write a bit of Clojure code that takes the first structure and transforms it into the second. Discarding information you don't want is usually easier than adding information that isn't there. Strings could be manipulated to remove characters that are illegal in ke

Ah, I was thinking the reverse: (clojure.string/split (name :foo->bar) #"->") But yes, you might be right. I guess the only thing I'd say is that the structure as it currently exists is sort of a bear. It just "feels" too big, like there's a more modular solution, but maybe it's not necessary?

In this case the for gives you the destructuring, plus the ability to do filtering (:when) and mapping (yeilding the value of i) in one expression. So you have one destructured binding that you can use for both purposes. If you want to use filter, I think it is probably more idiomatic to follow
