    172172Defines a new record property accessor {{RTP}}, optionally passing a
    173173{{DEFAULT}} to {{make-rtp}}.

     175<syntax>(define-record-printer (RTD . ARGS) . BODY)</syntax>
     176<syntax>(define-record-printer RTD EXPR)</syntax>
     177
     178Defines a record printer for direct instances of {{RTD}}.
     179
     180In contrast to the built-in form of this macro provided by the CHICKEN
     181standard library, {{RTD}} is interpreted as an identifier bound to a
     182record type descriptor, not as the unique identifier used to tag
     183instances of the record type.
