|An abstract interface to a unique symbol generator.
|An abstract unique object. Objects of type Unique may be
compared for equality and ordering and hashed into Int.
|Creates a new object of type Unique. The value returned will
not compare equal to any other value of type Unique returned by
previous calls to newUnique. There is no limit on the number of
times newUnique may be called.
|Hashes a Unique into an Int. Two Uniques may hash to the
same value, although in practice this is unlikely. The Int
returned makes a good hash key.
