(define (rec break fin do inc) (lambda (x) (let loop ((x x)) (if (break x) fin (do x (loop (inc x))) I wanted to make an implementation of the idea in near the bottom of http://www.paulgraham.com/power.html help! years truely, sunnan ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
[Chicken-users] Chicken mode for Emacs?
Hi everyone, is there an Emacs mode available that will run csi as an inferior Emacs process (preferably with syntax highlighting)? Starting csi from eshell isn't so cool...

Starting csi from eshell isn't so cool... [...] Hello, standard Emacs distributions usually include support for starting an inferior Scheme process using the run-scheme interactive lisp function. You can set the program that will be launched by that function through the customizable variable scheme-program-name. cu, Thomas ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users

If you absolutely must use rec as a name for something different, try unbinding the macro using (undefine-macro!

You can choose the Scheme interpreter you want to use (Quack - Options - Default Program) then you just need to M-x run-scheme.
