Definition: A "lennilite" is a term used in programming to refer to an object that has no memory or data stored within it. It's similar to a nil value, but instead of having its own storage space, it stores only null values. In other words, a nil value is not a real value, but rather the result of a computation that results in a false statement. This can happen when there are no valid inputs or outputs for an operation, and thus, the result is undefined
