chouser@n01se.net said: Nothing dramatic in the attached patch. A couple things I was unsure about:

1. There are a couple places where walking through part or all of the vector is done by incrementing an index and calling .nth each time. Is it worth while to instead use a chunked seq of the vector?

2. In a couple other places I use the seq library: some and every? Neither of these use chunks. Is this acceptable? If not, would it be acceptable if those fns used chunks?

3. Why oh why are Iterator and ListIterator such terrible APIs? Ok, I'm not really unsure about that one...

chouser@n01se.net said: Oh, one more:

4. I used subvec on a gvec to implement subList. It seems to work fine since APersistentVector.SubVector just requires the underlying object to be an IPersistentVector, which of course gvecs are. This is ok?

richhickey said: This all seems ok as a first cut. I wouldn't do anything with chunks in here right now. subvec seems ok. some/every? we might reconsider at some point due to bootstrapping. But that is an implementation detail
