Description

Would something like this be useful/belong in Cats and if so where would it belong?

def const[A](a: A): ConstAux[A] = new ConstAux(a)
final class ConstAux[A] private[cats](a: A) {
  def apply[B](b: => B): A = a
}

Research direction

The issue names no files or tests and asks whether a universally quantified const belongs in Cats or where it should live. Start by reviewing Cats' existing constant and universal-quantification abstractions and API conventions. Done means reaching a project-backed decision about usefulness and placement, with the relevant tests or documentation identified.
