I do not understand something this example:

Hi all,
The next version of system 0.3.0 is ready and it is a matter of days before

Sounds like competing performance-wise with the JVM is extremely difficult.
My best guess is that a successful new Clojure implemention will have these
qualities:

I do not think we will extend into to support array sources.
If your source is a vector, then vector seqs are actually really fast and
into-array is probably not as bad as you think, however it won't apply the
xf.
into is just doing transduce internally though and transducers are agnostic

I've been working on a custom implementation of a map called a hist-map,
which keeps a history of additions and removals in its metadata, so that
full diffs are not necessary.
I want to make persistent and transient versions of this map. Both
versions should support certain common operations,
That is very good to know.

Hi,
The other day I was trying to do an
(into (long-array 0) xform some-vec)
which doesn't work, then I realized there is *into-array* for that,
