It is confusing! :) I apply "begin" to the name, not the token. What about auto-resolved keywords that begin with :: ? I think it is more consistent to apply the same rule to the name part of : and :: keywords (and ideally symbols). And there is no reason to define a "first character" rule if the first character must be ":". But all of this is immaterial - we currently allow keywords starting with numbers and seem to have decided this is ok.
