    PS: How about we add `write-watchers' to variables ?  These would be
        hooks that get called when a specific variable is `setq'd.
        It'd have "zero performance impact" if we put it in the "setq-ing
        a read-only variable" error handling path.

I don't like the idea of changing the semantics of Lisp variables
in this way.
