I forgot to mention, if you want a Clojure persistent data structure that
is efficient (O(1) or O(log n)) for all of these operations:
+ adding to/removing from beginning
+ adding to/removing from end
+ concatenating
+ splitting into two sequences, at any specified item in the middle
look at fing
Conj (http://clojuredocs.org/clojure_core/clojure.core/conj) does what
you need for vectors. It's behavior depends on the type of collection
passed, so if you did:
(conj '(1 2 3) 4) you would end up with '(4 1 2 3).
For vectors it appends to the end of the list, for lists the beginning.
On Sat,
Thanks.

conj adds an element to a data structure in a place most efficient for the
particular type of data structure. For lists, this is at the beginning.
For vectors, it is at the end:
user=> (conj (conj (conj '(1 2 3) 4) 6) 7)
(7 6 4 1 2 3)
user=> (conj (conj (conj [1 2 3] 4) 6) 7)
[1 2 3 4 6 7]

Is there something like:
(defn snoc[ col item ]
(lazy-seq
(if (seq col)
(let[ [f & r] col ]
(if (seq r)
(cons f (snoc r item))
(cons f [i
Hi all,
Ran into what appears to be a bug tonight. This is the simplest example I
could come up with:
(defn f [xs]
(match xs
[:a] "a"
[:b b] b
[:c] "c"
:else "problem!"))
[:a] and [:b b] can be matched with no problems, but [:c] can't be matched
for some
Alternatively you can just do:
$ lein plugin install swank-clojure 1.3.3
and have swank across projects without having to add your
:dev-dependencies for each one.
