Thanks for the info!
I found that if I use AnyObject instead of Any, it does work correctly. Is that
because AnyObject isn’t a protocol? Or because conversion to AnyObject is a
‘magic’ case that uses Obj-C bridging?
My intuition is that [Any] will be more efficient than [AnyObject] for
primitive values like numbers, because the AnyObject conversion boxes the value
into a heap object, while converting to Any doesn’t. Or is that incorrect?
