Thanks.  Here's a fun one:

     >>> from peak.rules import when

     >>> def foo(X, Y):
     ...     print "default"

     >>> @when(foo, "X is None and not Y")
     ... def footest(X, Y):
     ...     print "footest"

     >>> @when(foo, "X is None and Y")
     ... def footest2(X, Y):
     ...     print "footest2"
