Attached is another version that adds: better error messages everywhere #:super #:property #:guard #:inspector #:transparent #:prefab compatibility with define-struct [you can use an sstruct as a struct parent] compatibility with scheme/match's struct expander [you can use an sstruct as a struct arg]
All with more tests, of course.

My #:super doesn't work the same as define-struct's.
I still don't support #:omit-define-syntaxes or #:omit-define-values.
I don't support #:auto. But should I since I allow default-value expressions?
I'm not sure what else is needed. Would we want to use this as the
default define-struct in #lang racket? Or should I put this in
unstable or on planet?
