Nice Find.

I think we can afford to be a little clearer about the difference between checks on the candidate's context (i.e. where it would be called from) vs its content (the instructions inside it), but maybe that's not helpful as when looking at the instructions most of our analysis is about e.g. liveness.

I'm not sure we need to fix the costing issue today, but I'm not sure.
