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?

I'm a bit confused as to exactly when symbol capture will occur with clojure macros. Suppose that I have a macro which defines a function from keywords. In this trivial example, (defmacro foo [keywd1 keywd2] `(defn ~(symbol (name keywd1)) [~(symbol (name keywd2))] (* 2 ~(symbol… >>> More

Does R6RS or Chez Scheme v7.9.4 have a library function to check if a list contains duplicate elements? Alternatively, do either have any built in functionality for sets (which dis-allow duplicate elements)? So far, I've only been able to find an example here. The problem with that is that it doesn't… >>> More
