		* If `setOnce` is true, then you'll be able to set property only once.
		* If used in combination with a `default` and you instantiate without that value, the default becomes the first value `set`. Thus cannot be set again.
		* If you don't have a default and don't set the value initially it can be set later, but only once.
		* Trying to set a property to an invalid type will raise an exception.
