Hello,

Andy Wingo <wingo@pobox.com> skribis:

The problem with this is that one could precisely forge instances of a
given record type, thereby breaking the type safety we currently have
(each instance of a record type is genuine, in the sense of Rees’ “A
Security kernel Based on the Lambda-Calculus”.)

Does Racket address this somehow?

Thanks,
Ludo’.
