Is Mule upwards-compatible with Nemacs/Emacs?

Although Mule is based on GNU Emacs, they are slightly different at the level of emacs lisp. Mule is quite different from Nemacs. Enami TSUGUTOMO &ltenami@sys.ptg.sony.co.jp&gt points out the incompatibility between Mule and Nemacs/Emacs as follows: • Incompatibility caused by the existence of functions specific to each program • Incompatibility caused by the modifications to function definitions (number of arguments, etc.) • Incompatibility of byte compiled files caused by the difference of the internal representation between Mule and Nemacs. Their byte code is compatible, however. (isn’t it? 🙂 • Incompatibility of compiled emacs lisp files caused by the representations of literals between Mule 1.x and Mule 2.x. • Incompatibility caused by the difference of versions of GNU Emacs they are based on.
