Why, what's wrong with func TraverseParTuple10[F1 ~func(A1) ReaderIOEither[T1], F2 ~func(A2) ReaderIOEither[T2], F3 ~func(A3) ReaderIOEither[T3], F4 ~func(A4)

- mseepgood 3y agoWow, this looks like Rust
- sambeau 3y agoExactly, I can’t wait to force this on my junior programmers and make them look stupid. cracks knuckles over keyboard

- cleue 3y agoThis is also one of my favorites, but it can get even more verbose. However this is how the go type system is designed to work with covariance. Without the `~` operator these functions could only be used for a much smaller range of inputs. But this complexity is an implementation detail of the library, you do not have to understand it as a user of these functions. From my perspective it is a valid approach to move complexity from use application layer into the library layer, so it can be hidden there and tested once.
