When interfaces were introduced I thought they would make the use simpler,
but that didn't happen, because re-use was thrown overboard. Limited
results and aggregates was an obvious miss. The mentioned features look
much like hacks.

This one is helpful, I ran into this one or two times.

I don't care about iterators and accessors, they IMO are just
misconceptions coming from languages with pointers.
