> I think it interprets &key as a name of a simple argument.

This can be a gotcha, for someone coming from
another Lisp dialect that supports lambda lists
with &key.

Perhaps Emacs Lisp could post a warning (e.g. from
the byte-compiler) if a lambda list uses one of the
`&' keywords supported by, say, Common Lisp (&key,
&aux, &allow-other-keys)?
