On March 2nd Arno Schödl from think-cell is presenting his talk “Why Iterators Got It All Wrong — and what we should use instead”.

After the talk, all attendees are cordially invited for a burger and drinks at the holy cow (Lowenstrasse 51) - sponsored by think-cell.

Abstract:
You understand iterators, right? How would you describe them? "Iterators are used to point into sequences of elements." Sounds good? More recently, the concept of ranges has been introduced to mean anything that exposes iterators. In particular, ranges include range adaptors for lazily transforming or filtering sequences of elements, and they, too, have iterators.
All good? Unfortunately, no. The iterator concept, which we have been using since the advent of C++, is fundamentally flawed. In particular, some iterators must behave differently depending on whether they are meant to point at an element or at a boundary between elements. So elements and boundaries are really two distinct concepts. In this talk, I will convince you that the problem is real and has practical implications, make a proposal on how to fix it and show how the solution not only fixes the problem but makes for clearer code and prevents mistakes.
