Possible Future Local Variables
===============================

   We have considered the idea of bindings that are local to a category
of frames--for example, all color frames, or all frames with dark
backgrounds.  We have not implemented them because it is not clear that
this feature is really useful.  You can get more or less the same
results by adding a function to `after-make-frame-functions', set up to
define a particular frame parameter according to the appropriate
conditions for each frame.

   It would also be possible to implement window-local bindings.  We
don't know of many situations where they would be useful, and it seems
that indirect buffers (Note: Indirect Buffers) with buffer-local
bindings offer a way to handle these situations more robustly.

   If sufficient application is found for either of these two kinds of
local bindings, we will provide it in a subsequent Emacs version.
