Do you think I should add this to the Wiki documentaion, since it 
differs from Java behaviour, or will it be changed eventually?

There's nothing magical about JUnit Assert, it just throws an Error if 
it fails.  I'll look at Nice assert or just pull the methods out on 
JUnit Assert into Nice.

The test* methods don't need to be static.  It appears the only way to 
be able to call Nice from Java "normally" is to have your Nice class 
extend a Java class and/or implement a Java interface.  Java won't let 
you implement an interface method as static.  So I don't think making 
these methods static is a good idea (or maybe not even possible with 
the byte code verifier...).

I just like being able to use the JUnit plugin that's integrated into 
Eclipse.  I'm haven't figured out if it's worth the hassle of writing 
these extra interfaces.   Thanks for your help.
