Yay indeed!

BTW, here's a real-world example of why eliding the stack trace is bad
news. I'm using deep_test and I've got a bunch of ruby classes that
are all communicating with each other. Can you tell me which class/
line of code of mine or of deep_test is provoking this exception?

Didn't think so :-)
