poly-arity

HList provides many operations to create and manipulate heterogenous lists (HLists) whose length and element types are known at compile-time. HLists are used to implement

  • records

  • variants

  • type-indexed products (TIP)

  • type-indexed co-products (TIC)

  • keyword arguments

User code should import Data.HList or Data.HList.CommonMain for a slightly more limited scope
