How can I write the following macro in Guile:
(define-syntax defpoint
(syntax-rules
()
( (defpoint p) (display "ERROR"))
( (defpoint p p-tupel) (define p (apply point 'p-tupel)))
( (defpoint p p-tupel pp ...) (begin (defpoint p p-tupel) (defpoint pp
...)))))
Another question: Is there a "scm_c_eval_file"?
TIA,
--

Just like that.
However, you must first:
(use-syntax (ice-9 syncase))
