Prevent empty values

[Palpie]

I would like an option to prevent empty values. With the option you would not have the Empty field and trying to create a new instance with an empty value would result in an ArgumentException being thrown.

You can kind of do this by creating your own template, as described in this post and this issue 🙂

One problem you will have is that you can still always create an instance of the type with the default keyword.
