I'm I the only who is annoyed by the introduction of Xemacsisms and
i would put it different: there are some quite useful functions (like set-keymap-parents) that happen to be available in xemacs but not in gnu emacs. therefore they are optionally defined to avoid redefining them when running under xemacs.
i could have added it as slime-set-keymap-parents which would have been even worse, imho.
In my opinion, this solution would be preferable.
as of defun*: i think that keyword args make the code much more readable than using optional parameters, especially when there are several optional args.
I have been using defun* myself in SLIME code. The Emacs Lisp code of SLIME contains many CL-isms; could people (Helmut, Edi) please comment what is the specific problem with defun*? Cheers, -- Matthias Köppe -- http://www.math.uni-magdeburg.de/~mkoeppe
