We have said that closures in Ruby can be used to implement the Command and Strategy patterns. Closures are useful in implementing various other design patterns too. Explain which patterns, and give examples, using pseudo-Ruby code (i.e., your code should illustrate how to solve the problem with closures in Ruby, but it doesn't actually have to run, if it would be too complicated to give a running example).
