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.
