[PATCH] D49956: [ADT] Add an early-increment iterator and range adaptor.

Yeah, that's vaguely frightening as a thing (I mean, yeah, the assertions help catch misuse - but still).

Got a pointer to an example of where you want to do this? Any chance of inverting this into a lambda-driven algorithm instead, maybe?

  pre_inc_for(R, [&](const auto &V) {
    ...
  });
