Can you give us a brief feedback on the kind of problems you faced with DEBUG set to 0? Or the reasons that motivated this move.

No real problems. It just turned out that with (DEBUG 0) tools like SLIME couldn't show the arglists of CL-PPCRE functions which is a feature that I like to have. Also, from tests with CMUCL it seems that you don't loose performance due to this change.

Personally, I still would like to know of an easy way to change these settings. For example, if something like the following would work: (defun frobnicate (frob) (declare (optimize (speed *cl-ppcre-speed*) (debug *cl-ppcre-debug*))) (twiddle (this frob)) (tweak (that frob))) A while back, when I was having my Lisp run-time die in some code that was using CL-PPCRE, I went and changed all of the optimization settings for saftey/debug to get some kind of stack trace, but I had to find/change all of the settings with Emacs. There has got to be an easier way to do this; is there really no Common Lisp paradigm for this? I've tried asking on comp.lang.lisp but don't remember getting a reply. Would one have to write a macro? (defun frobnicate (frob) (with-declaration ((speed-level *cl-ppcre-speed*) (debug-level *cl-ppcre-debug*)) (optimize (speed speed-level) (debug debug-level)) (twiddle (this frob) (tweak (that frob))))) -- Damien Kick
