union: Extensible type-safe unions
Extensible type-safe unions for Haskell with prisms using modern
GHC features. Dual to vinyl records. Unions are also known as
corecords or polymorphic variants.
Neither requires a Typeable constraint nor uses unsafe coercions
at the cost of linear time access (negligible in practice).
