My preference:
  head - rhead
  next - rnext (or advance - radvance)

The purpose of "retreat" and "toe" is to allow reverse iteration.
"retreat" in not the opposite of "advance"/"next", it's the same
operation applied to the other end of the range.  So why not make this
explicit by prefixing an 'r' to these reverse iteration functions?
