This is a pretty easy case right? Just a situation where we have a
atomic-to-nonatomic cast 'around' a non-atomic-to-atomic cast (or vice versa).
Can we just come up with an example?
Alternatively, and not something we can do now (as we're not really modeling
these casts?!), this seems like something that we could do as a opt in CIR :)
