As with these end checks, what if dereference would throw exceptions? End checks gone, all the way up the stack...
The problem happens way before dereference: it's the undefined behavior that results from even moving the underlying iterator past the end of the underlying sequence.
Using Arno's suggestion, dereferencing the end iterator ought to throw, which happens before we increment off the end, right?
The *underlying* iterator? How are you going to get that to throw if it's a pointer?
It sounds like he's proposing making iterators work the way they do in python.
