[Chicken-users] Error: unbound variable: define-macro

[Daniel Ajoy]

I pasted this code:

(define-macro (ez-debug var)
    (let ((name (symbol->string var)))
      `(print ,name ": " ,var)))


from

http://wiki.call-cc.org/chicken-for-ruby-programmers#macros

and got

Error: unbound variable: define-macro
