Methods of Copying
The design goal of most objects is to give the semblance of being made out of one monolithic block even though most are not. As objects are made up of several different parts, copying becomes nontrivial. Several strategies exist to attack this problem.
Consider two objects, A and B, which each refer to two memory blocks xi and yi (i = 1, 2,...). Think of A and B as strings and of xi and yi (i = 1, 2,...) as the characters they contain. There are different strategies for copying A into B.

“Methods of thought which claim to give the lead to our world in the name of revolution have become, in reality, ideologies of consent and not of rebellion.”
—Albert Camus (1913–1960)
“A woman might claim to retain some of the child’s faculties, although very limited and defused, simply because she has not been encouraged to learn methods of thought and develop a disciplined mind. As long as education remains largely induction ignorance will retain these advantages over learning and it is time that women impudently put them to work.”
—Germaine Greer (b. 1939)
“The young always have the same problem—how to rebel and conform at the same time. They have now solved this by defying their parents and copying one another.”
