`Nothing` should always evaluate to false to not accidentally render a block just because a not existing reference has been made by mistake. That means `not Nothing` has to be still `false` not `true` in a boolean context like a case.

There is a special function to explicitly check for nothing that evaluates to `true` like: `notexists `.

Is it helpful to introduce a `NothingNature` sothat function can check this special case ?
