Re: (aset UNIBYTE-STRING MULTIBYTE-CHAR)

[Richard Stallman]

    While I don't consider Python as the best design by far (the lack of
    type system rules it out right away), Elisp's dynamic scoping mixed with
    buffer-local and frame-local and terminal-local variables is pretty
    horrendous,

I think it is elegant.  Dynamic scoping is absolutely essential for an
Emacs-like editor, as explained in the Emacs paper from 1981.
