How is this used?

Hi! I'd just like to know the usage of this, please.

Hello! I'm not aware of any real world applications and use cases at the moment.

However, that is not what this library is for. This library exists only to defy the rules of .NET and do the impossible. Even though, as previously stated, this brings no practical benefits.

Just a heads-up, there is discussion about bringing a unit type in C#, like in other languages. void is the perfect candidate for this, and in a future version void could be a legal type to use. By that time, you can consider it your "unit" type, if you pass values through object.
