Hmm, interesting.  I'd rather put the name of the function in yet another
variable (WIDGETFUNC ?) and have it available for "zle -C" widgets, too.

For "zle -N" widgets, I think WIDGETSTYLE should initially be unset, so it 
can be tested with [[ -z ]] to differentiate completion from "normal" when 
inside a widget function.  (If it's just the function name, there's no way 
of preventing a function having the same name as a builtin widget, thereby
confusing matters.)
