refr makes it possible to store and change variables in the current scope, it can also be used as a StrongRef object.
Keep in mind that using Reference to a local variable will keep the scope alive, thus keeping alive all the objects referenced in that scope, so use it carefully.
retarded is a simple gem that lets you create a Retarded object by passing a block, as soon as a method is called on it the block is executed and its return value stored and it will keep proxying method calls to that return value.
