 The Eglot generic function machinery will automatically destructure
 the incoming message, so these two properties can simply be added to
 the new method's lambda list as @code{&key} arguments.  Also, the

 The remainder of the implementation consists of standard Elisp
 techniques to loop over arrays, manage buffers and overlays.
