I do know, and I disagree with this decision.

FWIW, repr(obj) is mostly syntactic sugar for obj.__repr__(), 
getattr(obj, name) for obj.__getattr__(name), type(obj) for 
obj.__class__  etc... IOW, we do have a lot of builtin functions that 
mostly encapsulate calls to __magic__ methods, and I definitively don't 
understand why this specific one (=> callable(obj)) should disappear. I 
usually have lot of respect for Guido's talent as a language designer 
(obviously since Python is still MFL), but I have to say I find this 
particular decision just plain stupid. Sorry.
