  I do see that when num3-mode is already enabled (turn-on-num3-mode) did

the turn-on- thing is a convention from emacs 23 and earlier.  yeah, looks like it should go away, and the logic of calling (num3-mode) from lisp might need to be fixed
 
I'm not sure what the "-num-" prefix is meant to be and I'm not fond
of it.  If it's meant for internal functions, then please use
"num--" instead.

yeah that's my fault, I've been flipping back and forth between using -pkg- and pkg--, and at the time I wrote num3 I was using -pkg-, and I prefer pkg-- now.
