Re: list definitions.  That's been tried before and backfired.  When
people did agree on a definition for all uses the newcomers wouldn't
know it or people would forget and then the admonitions would start.
Most times definitions weren't agreed upon and fights arose about the
possibilities.
 
Better if folks just realize that in lists as in the rest of life there
are several ways to interpret many things said or written.  A person
who can't remember that on list is going to have trouble with that same
lapse in outside life so...
