I guess I'm used to treating them like subroutines, but that may be naughty behaviour since I'm not sure return is exactly what I want, in fact I'm fairly sure it isn't, as a way of halting processing of a policy based on condition checks.

  Policies aren't subroutines.  They're essentially copied in place.

  Note that they're not *documented* as subroutines.  We hope to fix that for 4.0.

  Nope.  Just use if/else.  It's imperfect, but it works.
