This has grown quite beyond merely implementing $SUBJECT,
which are only the last 8 patches of the set.
Version 6 fixes a tcg problem with indirect global lowering,
and adds a test harness and regression test.
Version 5 addresses all of the feedback from v4, fixes some
further bugs in the base exception handling, implements
some missing exceptions.
