Hi Dave,
Thank you for your email.

You misspelled "distance_to."  Fix the spelling and it should work better.
Indeed a typo. Unfortunately, changing it to the method below does not
change anything. The method is never called even though I explicitly
call std::distance(), which, I assume, should call eventually
distance_to(),
facade_t::difference_type distance_to(const
data_stream::const_iterator & to) const
   {
     abort();
   }
Not unless yours is a random access iterator.  Is it?
