It's not a perfect superset of Algebraic and Variant in Phobos, 
so it's not a strictly better alternative. The feature that is 
missing is SumType can't hold arbitrary types, only the types 
specified in its template parameters. However, for the case where 
the set of possible types is limited, it's strictly better.
