          Issue ID: 21993
           Summary: Cannot cast to noreturn
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: minor
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com

`cast(noreturn) <exp>` is specified as `<exp>, assert(false)`.
But DMD rejects the cast with `cannot cast ... to noreturn`
