For example, Hash.new can be given a block in which you provide a default 
value. Assuming that there is a class called Something:

h = Hash.new { Something.new }
a, b, c = h[0], h[0], h[1]

a, b and c will contain three non-equal instances of Something, because 
every time h#[] is called, the block will be called.

Any chance that we see your real name?
