- TYPE-FIELD-ref AREC TNXprocedure
Return a reference for use with CELL-REF (alias "@") and ALTER!.
Note: Try to use this accessor just once per object+field. Multiple calls (within a lightweight transaction) will produce independent references. (If these become inconsistent, the commit will fail nevertheless.) Only those references used to (set! (@ REF) val) will return the in-transaction value.
