Nope, you're right. However, the reason I mentioned operator* was to
emphasize that the operators, whether * or == applied to values, not
types. The operator== applied to std::vector<I>::iterator and
std::vector<I>::iterator would probably compare an I* with an I*
and not use:

   is_same< std::vector<I>::iterator, std::vector<I>::iterator>::value

I'll admit I shouldn't have mentioned anything about length; however,
if two stl iterator's do compare equal then the operator* would
return the same value for the same number of operator++'s, wouldn't
