[swift-evolution] Casting Bug Swift

Say I have been passed an array of objects that conform to a protocol
called "Eatable" i.e [Eatable]

If I then try to cast them to an array of classes who happen to implement
that protocol i.e [Burger]

The compiler lets me but in the runtime it corrupts the memory.
