No, I think OP would mean that that reference might be bound into the 
arbitrary function (functor). Or another iterator to compare to might 
be. Or a test for equality of the derefernce with another object. Or, 
for some iterator classes, end() might be constant across containers, 
and no binding is necessary.

I agree the generalization would be a good thing (I'd use it! I've been 
salivating for a more solid Range class, and one better integrated with 
containers/algorithms), but care needs to be taken that the easy/usual 
cases aren't made harder by doing it.
