I see,thanks. Pallet is more powerful than clojure-control.It seems that it contains many features for cloud service rather than just a deployment tool. And clojure-control is just a deployment tool like fabric in python for many machines using SSH,it can reuse tasks and clusters,and have a simpl

Re: why does Clojure need to cache keywords?

I think this cache is just the same with String.intern method in java,it just want to reduce the cost (memory & cpu) of producing keywords frequently especial when using them with map structure. 2012/7/18 jaime > I doubt because keyword will use its internal Symbol object to compare > with each

Re: Question about doseq

Please use prn insteadof println. By default, pr and prn print in a way that objects can be read by the reader,but print and println produce output for human consumption. 2012/10/31 arekanderu > Hello all, > > I have the following code: > > (def my-hash {"1" {:a-key {:value "a value"} :another-k
