I've only ever used posing in monitoring or testing code replacing a  
real class with a mock replica - i.e. where not much is going on, and  
I have full control over it.  The only other example I've seen is in  
decorating view objects (i.e. [GLFancyButton poseAsClass: [NSButton  
class]]), although I can't remember the context and remember thinking  
it was a bad idea back then.  So I've got no strong reason to mourn  
the passing of +poseAsClass: ;-)
