The exception mechanism is also used to implement early returns by throwing and catching return values: A function body with one or more early returns of type @{typ 'a} (and exception type @{typ 'e}) is lifted to a monadic expression with exception type @{typ "('a + 'e)"} using -@{term liftSR}, such that an early return of the value @{term a} throws @{term "Inl a"}, and a +@{term liftRS}, such that an early return of the value @{term a} throws @{term "Inl a"}, and a regular exception @{term e} is thrown as @{term "Inr e"}. The function body is then wrapped in @{term catch_early_returnS} to lower it back to the default monad and exception type. These liftings and lowerings are automatically inserted by Sail for functions with early returns.\<^footnote>\<open>To be |
