Procs, Lambdas and closure.

We are all use blocks in our ruby programs, but what if we`d like to store somewhere or pass anonymous code to some method.
It is neccessary to do for example in Strategy pattern, where
1) we are defining or load some strategies;
2) we are passing one of strategy to object to call some action;
For that purpose Proc and lambda are very usefull.
