And now it's better to start using "immutable" instead of "invariant" that is
probably deprecated. I guess "invariant" will be removed in some time.

Basically, is(typeof(X)) is D magic.
One could interpret it as 'is X a valid type', or perhaps more
correctly as 'does X compile'.

Here a explicit tuple is needed.
