## Constructors

### Void

Void();

Creates the Void.

### Void

The philosophical aspects of this operation remain undiscussed for now.

## Destructor

### ~Void

~Void();

Destroys the Void.

bool operator != (
const Void & v
) const;

Will return always false due to Voids having no members.

### operator =

Void & operator = (
const Void & v
);

Assigns another void.

### operator ==

bool operator == (
const Void & v
) const;

Will return always true due to Voids having no members.
