And this is exactly my use-case: a variable whose value will be periodically changed. And I don't like the hassle of having an option to a separate file with just this one variable... Of course, if the only user beside me won't like Emacs messing around with his init.el, I'll do it that way. Thanks! -- Marcin Borkowski http://mbork.pl
