After the recent change of adding easy-menu-define in scheme-mode,
when the init file contains the line:

  (require 'cmuscheme)

loading Emacs fails with the error

Debugger entered--Lisp error: (wrong-type-argument keymapp nil)
  define-key(nil [separator-eval] ("--"))
  require(cmuscheme)

This should now be fixed on the trunk (well, the FSF server are very
slow today, so I'm having trouble pushing anything), but...  that
cmuscheme.el file is rather odd: It doesn't create a new mode or
anything, but just alters the scheme.el mode things, which means that
after you've loaded it, you can't use the regular scheme.el mode any
more.

Which is a very unusual way of doing things, to put it mildly.

Thanks, confirmed.

cmuscheme.el is valuable for one thing - the command 'run-scheme'.
