Initial response to feedback from Norbert, Makarius on record patch As Norbert recommended, the IsTuple.thy and istuple_support.ML files have been integrated into Record.thy and record.ML. I haven't merged the structures - record.ML now contains Record and IsTupleSupport. Some of the cosmetic changes Makarius requested have been made, including renaming variables with camel-case and run-together names and removing the tab character from the Author: line. Constants are defined with definition rather than constdefs. The split_ex_prf inner function has been cleaned up.
