Or patterns would be nice to have. For example, to write the code below without them we'd need helper methods which adds to syntactic noise.

function method foo(doc: Doc): nat {
    match doc
      case Empty | Line => something complicated
      case X1 | X2 | X3 => something else complicated
  }
