I find it somewhat annoying that I cannot see the arglist information for functions while in the SLIME debugger. Is it possible to change SLIME-BUSY-P so that SLIME-AUTODOC-MODE and SLIME-SPACE will continue to work while inside the SLIME debugger? To implement this, the SLIME-BUSY-P needs to know the rex-continuations for the forms that cause the debugger to be entered. The SLIME debugger needs to be able to figure out the rex-continuation of the form that caused the debugger to be entered and add it to the list in the global variable *SLDB-REX-CONTINUATIONS*. When the debugger exits, it needs to remove it from the list. SLIME-BUSY-P would become something like: (defvar *sldb-rex-continuations* nil) (defun slime-busy-p () "True if Lisp has outstanding requests." (let ((sldb-continuations *sldb-rex-continuations*)) (dolist (contin (slime-rex-continuations) nil) (if (not (memq contin sldb-continuations)) (return t)))))
