Is it possible to remove the asserts in derive that restrict the
parent and child to namespace-qualified names?
It would be much more useful if the asserts are moved to the global-
hierarchy case ([child parent]) and the private hierarchies ([h
child parent]) can do as they wish. Maybe ditch the

Hi folks,
As of clojure-contrib SVN 283, there's a new clojure.contrib.test-is.
This is a pretty major rewrite of the library. I've tried to
streamline the code and make it easier to plug in custom reporting and
assertion functions. Unfortunately, this introduces several breaking
changes:

Clojure sometimes throws exceptions that report a line number of 0

exceptions report the correct line number.

I'm using Clojure Box on Windows. It's working well for me, but I

2. How do I restart the REPL, so that any definitions are erased

I don't use Clojure Box or Windows; however, your questions relate
