The problem is that your first namespace defines 'sorted?' and your second
namespace just uses the namespace, thus overriding 'sorted?'. You have two
options here. Your biggest project is that you're using ':use'. Use

Thanks for the replies. I'm not the owner of what the official namespace
should be, so perhaps I'll just clj-xxx and I can always stop using that
and change with a major release milestone. Clearly too much thought has

Thank you for replying.
I see that using :require like (:require [random.learning.clojure.overridex

also means I have to use sorted? as o/sorted? else the

I think I have an idea of where your coming from. Leiningen does lots of

Yes, since this is runtime you should use reflection.

Alternatively, you can use eval:

You want either `reduce` or `loop` as the control flow construct, and
