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.
class Thing def square(n) n*n end end aThing = Thing.new aMethod = aThing.method("square") aMethod.call(9) → 81 [ 1, 2, 3 ].collect(&aMethod) → [1, 4, 9]
m = 12.method("+") m.call(3) → 15 m.call(20) → 32
Procobject corresponding to this method.
