I am trying to write a macro that defines a special class of data structure with associated functions.
I know this is possible; it is done multiple times in the core language itself.
As a specific example, how would I define the define-struct
macro in Scheme itself. It needs to create make-struct
, struct-<<field>>
, etc functions.
I tried doing this using define
, however, this only defines the function in the macro's lexical scope.
How can I actually define a function in a macro?
