 A run_time error I would say, with aborting the function.

 About the only use case I envision for this is when one knows for sure
 what field (w/ type) the record should have, and using the operator
 then just acts as dynamic check to make sure that's indeed the case;
 if it's not, that's a bug in the script because the function shouldn't
 have been called in the first place.

 That's also why I don't think I'd add a boolean "query operator" in
 addition (like the `rec?$<conn_id>cid`) as that would only encourage
 using it for dynamic dispatching based on type, which I don't really
 like.
