Just look at the changes made in > the Guile-Emacs repo to core Lisp files, and you will see what I mean. It's not a 100% drop-in replacement, that's true. I'll take a peek what changes in Elisp files it did; the only one I remember at the moment is Gnus directly writing out Elisp bytecode somewhere. > Btw, I admit I don't completely understand what the wiki says about > the problems with t and nil, but if that means you cannot say in > Guile-Emacs something like > > (if (eq foo t) ... > > then there are more than 700 places in Emacs that will stop working. (eq foo t) should always work. (eq foo nil) will only work if that `nil' came from Elisp code; if it's a Scheme #f or '() in disguise, then you need to make that (not foo) or (null foo) (both works in both cases); anything but (eq foo nil).
