in reply to A metaclosure? Howto?
I'd solve this using a class. The object instantiated would be initialized with a given value by the new() method (or by a default value) and then the value would be manipulated with a method, that would apply the required changes to the value and return the updated value.
I would also ask myself the question if I should implement this as a Singleton class, all depending upon the needs at hand.
Everything went worng, just as foreseen.
