// TODO: Change the name of __unwrap_iter_impl to something more appropriate
// The job of __unwrap_iter is to remove iterator wrappers (like reverse_iterator or __wrap_iter),
// to reduce the number of template instantiations and to enable pointer-based optimizations e.g. in std::copy.
// In debug mode, we don't do this.
//
// Some algorithms (e.g. std::copy, but not std::sort) need to convert an
// "unwrapped" result back into the original iterator type. Doing that is the job of __rewrap_iter.
