change a simple tree.
I'd like to multiply the odd numbers by 2 in this case.
https://gist.github.com/dabd/7666778
It looks like after editing the first (branch) node clojure.zip/next will
get to the end of the tree.
How can I correct this code?
Thanks.

Thanks. Do you think the call to z/edit in my code could be simplified? To
edit a branch node I have to use conj to build a node only to pass it to
make-node which will break it apart again.

I would like to implement an algorithm that works on trees (n-ary trees)
where each node is a complex type. Aside from the usual tree traversals I
will need to be able to access the parent of a node.
Performance is important since the algorithm is going to traverse the tree
several times and upd

see if you actually have performance problems first.

I am using the latest CIDER 0.6.0alpha (package: 20140224.735) (Clojure
1.5.1, nREPL 0.2.1) on Windows.
I noticed suddenly my repl started to miss some println messages in my code.
A simple test like this shows:

hello
It won't print the second message f
I defined this macro https://gist.github.com/4646206 that expands to a
function.
It behaves like this

false

I installed the latest 1.7.0_17 and apparently the issue is gone but I
still don't know what caused it.
Thanks.

It seems like 1.7 changed how default Locales are read from the host:

I have a NetBeans project where my REPL shows the following path in
the classpath:

clojure.lang.RT.loadResourceScript("foo/bar/baz.clj"), which is
located in /home/my-proj/src/clj/foo/bar/baz.clj with no problems.
