This is an improvement to #161, which implemented
Func
.AppFunc
data type implemented@&&&
method to composite two applicative functions producing another function that returnsTuple2[F, G]
. @larsrh suggested I usetypelevel
package, and thusFunc
was created to handle several typeclasses generically.@&&&
was refactored to useHList
, but it remained to handle only two items at a time.What this changes
As per @larsrh's suggestion, this provides composition that produces a function that returns n-item
HList
.
