It's "EvalReader". What it does is cause the expression to be

Why not make a list of numbers from 0 to max, randomly shuffle it,

In this scenario, I'd probably not try to fight maven and split this into

And the problem with the plain (keyword x) approach is how the

In 1.1. if I call (keyword 'foo/bar) i'll get :foo/bar. OK, because

If you have the clojure:compile goal bound to the compile phase it runs
-after- the normal java compiler. One solution I've used is just using
multiple modules and keeping the clojure code separate from the java.
However, if your only talking TO java from clojure this might not be a
problem.
