It woudl be easier for make-record-type records, since printing those already prints out the fields. So it's just a matter of checking for classes that extend kawa.lang.Record. Something similar could be done for SRFI-9 records, but it might take some changes in how they are implemented, to better support introspection. Using Java reflection is possible, though maybe expensive. -- --Per Bothner per@bothner.com http://per.bothner.com/
