Depends on 6 packages(full list with versions):

base, deepseq, hashable, profunctors, tagged, vinyl

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).
