Hi,

Andreas Fuchs recently pointed out[0] that Common Lisp files often have
a file-local variables section which specifies the package and syntax of
the code in the file. For example:

           -*- mode: lisp; package: cl-user; syntax: ansi -*-

Andreas does the following in his .emacs; perhaps these should be the
default (at least, for files in lisp-mode)?

,----
| (put 'package 'safe-local-variable 'symbolp)
| (put 'Package 'safe-local-variable 'symbolp)
| (put 'syntax 'safe-local-variable 'symbolp)
| (put 'Syntax 'safe-local-variable 'symbolp)
| (put 'Base 'safe-local-variable 'integerp)
| (put 'base 'safe-local-variable 'integerp)
`----

Why do people set those vars like you show?  I.e. which piece of code makes
use of that?

If we do mark these variables as safe, we had better defvar them too,
so that people won't think it is ok to define them for some other
meaning.

Another idea is to define something meaning "ignore this variable",
which would mean "don't bind the variable and don't complain about it
either."

Well...

 -- Variable: ignored-local-variables
     This variable holds a list of variables that should not be given
     local values by files.  Any value specified for one of these
     variables is completely ignored.

How about adding those to ignored-local-variables?

Before we do that, could someone reply to my question:

What are those variable settings used for?
I.e. which program/package/thing makes use of them?

As long as we don't know that, it's impossible to know what's the
best solution.

Why does it make a difference?  As long as the use isn't in Emacs, I
think the answer doesn't matter for us.

We don't even know if the use is in Emacs or not.

And if the OP can't be bothered to answer my question, I don't see why we
should go through the trouble to try and solve what he claims to be
a problem (do we even know it's a real problem, and not a pilot error?).
