> Why the minor modes variables are only t or nil?
Because that's how they've been defined. There's nothing magical about
minor modes, so you can definitely define something that looks and acts
very much like a minor mode but doesn't limit itself to boolean values.
Whether the `define-minor-mode` macro should offer a way to do that is
hence a UI design question. I can see the benefit of what you propose,
but I also see the benefit of sticking to this simple model.
[ I don't understand the choice of "Subject:" here, I must say.
What do minor modes have to do with syntactic sugar? ]
