What makes you say that there's something wrong with iterator_facade's
operator[]?  Is it possible that the regression test makes invalid
assumptions about the way an iterator's operator[] is supposed to work?

That's unneccessary.  Any iterator_facade behavior you want to replace
can simply be added to your derived iterator class.

Here we are!
