@abstract Case equality operator. @param [Stack] stack A Stack. @return [TrueClass, FalseClass] identity_equality True in the case self's object_id equals stack's object_id.

copy_constructor(). @abstract Copy constructor. Creates a clean copy. self and the copy share no object references apart from Ruby's singleton methods. @return [Stack] A copy.

push(data). @abstract Pushes data on the stack. @param [Data] data A data object. The data becomes the stack top. @return [NilClass] nil

def push(data)
end

size(). @abstract Getter. Gets self's size. @return [Integer] The size.
