Its a forward iterator. Changing it to a random access iterator solves
it indeed.
This is my first iterator that I am writing, but why is it not
possible to implement a custom distance method for forward iterators?
Am I doing something conceptually wrong? Or should I specialize the
std::distance() function?
Thank you,
Andrej
