 thought it was outside the scope of #2432 (see comment #32 on that ticket)
 and made it into another ticket.

 I don't know the details of BOOST_FOREACH, nor std::foreach. But I doubt
 they need it to be bi-directional (both foreachs go only forward). I guess
 we need:
  • Test that it works.
  • Add some typedefs and methods with names such that the foreach expects
 them.

 So I guess this would be mostly making the naming compatible. I don't
 think we're missing something functionality-wise, at least for read-only
 foreach (used with const referrence).
