	= Answer whether the receiver and the argument represent the same object. If = is redefined in any subclass, consider also redefining the message hash.
	hash Answer a SmallInteger whose value is related to the receiver's identity. May be overridden, and should be overridden in any classes that define =
	species Answer the preferred class for reconstructing the receiver. For example, collections create new collections whenever enumeration messages such as collect: or select: are invoked. The new kind of collection is determined by the species of the original collection. Species and class are not always the same. For example, the species of Interval is Array.
