Added four macros to racket/generic: - chaperone-generics - impersonate-generics - redirect-generics (dynamically chooses between the above two) - generic-instance/c All take pairs of method names and wrappers (procedures or contracts), and turn those into appropriate chaperone, impersonator, or contract wrappers on the method tables of the given structs. Used this to rewrite set/c to give better error messages. |
