Method

Method objects are created by Object#method, and are associated with a particular object (not just with a class). They may be used to invoke the method within the object, and as a block associated with an iterator. They may also be unbound from one object (creating an UnboundMethod) and bound to another.

class Thing
 def square(n)
 n*n
 end
end
thing = Thing.new
meth = thing.method(:square)
meth.call (9) #=> 81
[ 1, 2, 3 ].collect(&meth) #=> [1, 4, 9]
