# Previously, we used :klass => Klass instead of :klass => :klass.

# most it would continue to work. Other stuff, unfortunately, would
# break horribly. (Integer.new, for instance, makes Ruby very angry.)
# The purpose of these tests is to verify that everything _either_ 
# breaks horribly or works, where the third option is fails silently
# and mysteriously.
