I was providing the original poster with a simple way to ensure 
appropriate type. You can assert whatever aspect you wish. If you want 
to ensure compatibility with some other property simply use "assert 
blah" subsituting blah for whatever test you wish to perform (e.g. 
assert MyInterface.implementedBy(bar) to test for interface implementation).
