I volunteer to ensure that the "/"s are added if this PEP is accepted.  
(I expect I'd do it myself, but who knows, maybe a volunteer would 
appear out of the woodwork.)

It has to be a different value from "None", for the same reasons that 
all those other different-spellings-for-None (e.g. 
inspect.Parameter.empty) exist.

I realize you are -1 on the proposal in general, but I'd be very 
interested if you could propose an alternate approach where I didn't 
need "a new spelling for None" as you put it.
