    So you argue for "turn it on" rather than "toggle".

Not necessarily.  This case should't be considered in isolation but
rather as part of an overall design for minor modes.

One design that occurs to me is (foo-mode) turns it on, (foo-mode t)
turns it on, (foo-mode nil) turns it off, and the way you toggle is
(foo-mode (not foo-mode)).

Another is (foo-mode) toggles, (foo-mode t) turns it on, (foo-mode
nil) turns it off.

I am not sure which of those is better.  I don't think we should
reject either out of hand.

The current convention for interactive calls seems clear and natural
so I think it should be preserved, whatever we do with calls from Lisp.
