trait
DefaultMap[A, +B]
extends Map[A, B]
A default map which implements the updated and -
methods of maps.
Instances that inherit from DefaultMap[A, B] still have to
define:
def get(key: A): Option[B]
def iterator: Iterator[(A, B)]
It refers back to the original map.
It might also be advisable to override foreach or
size if efficient implementations can be found.

|
+
[B1 >: B](kv : (A, B1)) : Map[A, B1]
