A TypedMap is an immutable map containing typed values. Each entry is associated with a TypedKey that can be used to look up the value. A
TypedKeyalso defines the type of the value, e.g. aTypedKey[String]would be associated with aStringvalue.Instances of this class are created with the
TypedMap.emptymethod.The elements inside TypedMaps cannot be enumerated. This is a decision designed to enforce modularity. It's not possible to accidentally or intentionally access a value in a TypedMap without holding the corresponding TypedKey.
