This is definitely cleaner than the old code, but what would you think about a function that tests a specified flag? So rather than

`op.setNoUnsignedWrap(any(ob & OverflowBehavior::NoUnsignedWrap));`

you'd have

`op.setNoUnsignedWrap(testFlag(ob, OverflowBehavior::NoUnsignedWrap));`

Obviously this is minor and could be a future change if you think it's a good idea.
