The make sense part is:

Given the code below, I'm wondering why I get

I'm just trying to understand why I would use :>> in a condp expression. The

remains. Why would I want to use :>> ?

Hi,
the import syntax for the java libs in the correspondig clojure
contrib source is wrong. Just change them to the correct syntax and it
works.
At least that worked for me.

The following code works for me. read-input returns nil if the socket

I still have some problems to correctly understand the dosync

list:
Example
thread 1:
(dosync
append an item to a list

thread 2:
(dosync
remove an item from a list

)
Is it true that If thread 1 is

The only reason I can think of: It could be a problem when the loading

explain why calling
