+The output can optionally be an assignment with a type annotation:

 - Good, because input block syntax mirrors the top-level `record` definition.
 - Bad, because two different notations for the same concept in the same process definition.
 - Bad, because `Record { ... }` block syntax only exists in input declarations — it is not a general-purpose construct.
-- Bad, because output `record()` as a bare statement (no assignment) doesn't allow naming the output.
 
 ### Option 2: Block syntax for both inputs and outputs
