/// @assertion bool operator ==(other)
/// The equality operator.
///
/// The default behavior for all Objects is to return true if and only if this
/// and other are the same object.
///
/// Override this method to specify a different equality relation on a class.
/// The overriding method must still be an equivalence relation. That is, it must
/// be:
/// ...
/// Transitive: For all objects o1, o2, and o3, if o1 == o2 and o2 == o3 are
/// true, then o1 == o3 must be true.
/// ...
/// @description Checks that for all objects o1, o2, and o3, if o1 == o2 and
/// o2 == o3 are true, then o1 == o3 is also true.
