Agreed, but they also complained about map() and flatMap(). I have to think that eventually every developer can understand the more straightforward monads, functors, and Either - which, along with type aliases, IMO, can make code a lot more readable.
I think the more esoteric features should be reserved for complex code, especially if it's possible that those features can prove runtime correctness at compile time and result in easily-composable modules. I wouldn't expect more than one or two developers to need to develop such a subsystem, however, so the "clever" is used in isolation.
