Hi, from the docs on #:methods argument to struct:
"If #:methods gen:name method-defs is provided, then gen:name must be a transformer binding for the static information about a generic group produced by define-generics. The method-defs define the methods of gen:name. If any method of gen:name is not defined, then #f is used to signify that the structure type does not implement the particular method. [...]"
Can anyone explain the part with the #f to me? Does it mean that i have to (define some-gen-fun #f) to indicate it's not implemented? But that seems to have no real impact as i get the exactly same error with just leaving it out?
Thanks for any clarification.
