MaybeVoid# (a :: ZeroBitType)unlifted Data.Maybe.Void Unboxed variant of Maybe. The thing possibly contained by Just has a void runtime representation. Rather than using a sum, like the more general Maybe# does, this represents Nothing with 0 and Just with 1. It is recommended that the data constructor not be used directly. Prefer the two pattern synonyms.
