In a variation of a famous line of one of my favorite
former American presidents  "It all depend what the
meaning of it is" ;-)))

I assume that you are wondering if using ambiguity
resolution makes is a big change in the use of multi-dispatch?
No I don't think so, it is just a variation of multiple dispatch
(kind of similar to the in my mind minor difference between
overloading and the supposable evil multi-methods;-).
