Clojure can generate code every bit as fast as normal Java code, can 
call Java efficiently (if you use type hints), and can be called from 
Java (a Clojure function is an object implementing the IFn interface -- 
IFN foo = do-whatever-to-get-clojure-function; foo.invoke(arg1, arg2);

Furthermore, Clojure has an "immediate-mode" for prototyping, 
development, and even CLI-style tool use, called a "repl", and has 
Pythonesque list comprehensions, map, filter, etc. for working with 
lists and sequences of various kinds. Very handy.

The potential downside: it has a Lispy syntax -- prefix notation and 
parentheses around every function call. This can make math slightly 
annoying.
