Why not both?

With the recent announcement of cats-effect, a relevant question from the past resurfaces: why does IO, which is otherwise quite Task-like, not define both or race? To be clear, the type signatures of these functions would be as follows:

object IO {
  def both[A, B](ioa: IO[A], iob: IO[B])(implicit EC: ExecutionContext): IO[(A, B)] = ???
  def race[A, B](ioa: IO[A], iob: IO[B])(implicit EC: ExecutionContext): IO[Either[A, B]] = ???
}

Why stateless rendering is pure bliss

React just got stateless components, meaning that they are in essence pure functions for rendering. Pure functions make it dead simple - even fun - to refactor your views
