BatMap.PMapval (-->) : ('a, 'b) BatMap.PMap.t -> 'a -> 'bmap-->key returns the current binding of key in map,
or raises Not_found. Equivalent to find key map.val (<--) : ('a, 'b) BatMap.PMap.t -> 'a * 'b -> ('a, 'b) BatMap.PMap.tmap<--(key, value) returns a map containing the same bindings as
map, plus a binding of key to value. If key was already bound
in map, its previous binding disappears. Equivalent
to add key value map
