Judging by Apocalypse 5 it won't be possible to execute arbitrary code in rule actions. At least I can't find any examples of anything besides manipulating "hypothetical" variables, so maybe it will be memoizable.

Unfortunately after a quick look, I don't fancy digging through PIR, especially as that seems to be in very early stages and probably bearing no resemblance to it's final state.
