Warren,
I would ask myself (quite seriously, no snark intended) whether or not a
fixation on ordered collections or sub-collections woven throughout a program
(as you seem to be describing) is a language feature, or the responsibility of
the programmer.
Larry, Ulises, and Michael have all offe

This release contains backwards-incompatible changes in the both the API
and philosophy.
The primary change is that the imperative `unify!` function has been
removed in favor of a `unify` datatype that represents the same idea:

It seems the name "append" has not yet been taken. How about we do this
with Clojure:
1. add a new function "append", which splices multiple ordered collection
together and always returns the result in the concrete type of its first
argument. So:
(append [1] '(2 3)) => [1 2 3]
(append '(1) [2
Again, everything I wrote here is "in my view". (think of :injection ("In
my view")).
Thanks. I am certainly sure it is doable with Clojure, as you just did it.
The unpleasant thing is Clojure does not provide a built-in function for
that (which might be much more efficient), and the "sequence

OK, the complete silence leads me to believe that not many people reduce
with set/intersection.
However, I thought of a couple of other functions that don't work with the
new framework: max and min.

Thanks, but this does not keep the concrete type.

How about:

You can combine 'drop and 'drop-last to get a seq version of subvec (but

This combination of Sublime -text & -REPL looks pretty useful, with little
extra configuration (except that decommenting part :) ).
When I have the REPL launched, when returning values I get a lot of lines
with BS..BS sequences. Any idea how to get rid of those ?

I am surprised that there seems to be no general sub-sequence function that
will return a segment of a sequence without changing the underlying
concrete type. I found "subvec", but it works only on vectors. "subseq" is
not what I thought it is. Did I miss anything? Or is there a simple
