Let me try and be clearer:
A singular iterator (that is to say one that is default constructed) has
only one behaviour defined for it - you can assign to it a new value - and
that's all you can do with it. You cannot compare a singular iterator with
another iterator (not even another singular one), *unless* the particular
iterator type has some implementation-defined behaviour specified for that
For example the following is not legal code:
template <class Iterator>
Iterator a, b;
a == b; // illegal operation.
a == t; // also illegal.
