Yes, sorry... my response was already obsolete before I posted it.
Shouldn't count so much on my (also obsolete) mail reader's threading
capabilities to tell me when I'd read all messages on this topic.

(By the way, I think there's actually a place for both forms of the
assertXxxx() and failUnlessXxxxx() methods.  Sometimes the logic
just seems clearer to write it (and read it) one way, or the other.  
Perhaps that's a sign of smelly programmer thinking, but all I can do 
is report on what I've experienced personally...)
