I would recommend adding examples to clojuredocs.org and adding new
problems to 4clojure.com.

I am confused by your question. If you are looking for help on a
4clojure problem, you may post to the new Google 4clojure group
(http://groups.google.com/group/4clojure).
If not, please give more details on the skeleton of a tree problem and
I'm sure someone here can help.

Hint: use the take function.

Don't go further before it's too late and you are checking the website

Are you sure you are using the latest Clojure 1.2 version and not an
early beta, etc.?

I had a bug in my code where I meant to type:
(get map key)
and instead typed:
(get max key)
It seems that any function name I put in for "max" always returns nil.

Looking at the api code helped me a lot, for what it's worth.

I've been programming in large OO applications since about 1993.
One problem is that a lot of useful code gets buried way deep in an OO
class hierarchy, where you are forced to create lots of intermediate
objects just to get to the useful functions.
This really hurts the re-usability, unit testab
Sorry, that was TOO easy. Too many years as a Java programmer have
rotted my brain!.

Note
If I have a Java function that uses List or
Map, is there anyway to create these in Clojure the
same way I can create vectors or maps?
For example, if a function signature is:
void foobar(List x, Map y)
I can pass standard vectors and maps to it, but I can't figure out how
to do the same for th
