Russel Winder:
Practical experience, i.e. actually using it for real on real projects, indicates that Clojure is an excellent language and very usable.
In my very limited Clojure experience I've seen that it uses a LOT of memory even for my small programs, sometimes almost ten times more than equivalent Python programs (like 120 MB for a small program that processes small genomic text files). And I've seen to write fast Clojure programs I have to add a ton of annotations to the code. So I have not used it further.
