Vincent, Carl,

I stumbled on another workaround, defining the specific methods outside of 
define-generics, and then rebinding them withing #:defaults.
Anyway, it was only for a small exercise.

Thanks for the quick reply,

Bert

Bert,

I've just pushed a fix to this bug, which I had written previously as part of 
some other work I'm doing with generics.  As Vincent already pointed out, if 
you're using a released version of Racket and updating to the new code is 
problematic, you can always work around the bug with your own wrapper functions.



Thanks for the report,Carl Eastlund

Helo,

in the documentation it is mentioned that the syntax for define-generics 
#:defaults is the same as for struct #:methods:
http://docs.racket-lang.org/reference/struct-generics.html#%28form._%28%28lib._racket%2Fgeneric..rkt%29._define-generics%29%29


and #:methods specifies that define/generic can be used to bind the generic 
method:
http://docs.racket-lang.org/reference/define-struct.html#%28form._%28%28lib._racket%2Fprivate%2Fbase..rkt%29._struct%29%29



but unfortunately using define/generic in #:defaults is a syntax error.
Is it possible to access the generic method from inside #:defaults definitions?

Groeten,
Bert
