for `~str`/`~[]`. Note that `~self` still remains, since I forgot to add support for `Box<self>` before the snapshot. How to update your code: * Instead of `~EXPR`, you should write `box EXPR`. * Instead of `~TYPE`, you should write `Box<Type>`. * Instead of `~PATTERN`, you should write `box PATTERN`.
