Scalaz |-> counterpart in Cats

Question

I noticed that the Scalaz |-> operator is not implemented in Cats. Is there a function offering similar semantics?

Do you mean [this here](https://static.javadoc.io/org.scalaz/scalaz-core_2.11/7.2.2/index.html#scalaz.syntax.EnumOps@|-%3E(to:F):List[F])? — Andrey Tyukin, Jun 15 '19 at 14:16
Well, there is no good reason why `|->` should be in Cats, so it's not in there. — Andrey Tyukin, Jun 16 '19 at 16:35

"Herding Cats" tutorial recommends to use spire.math.Interval as Cats/Typelevel's replacement for scalaz.Enum.

So try to replace

import scalaz.syntax.enum._
import scalaz.std.anyVal._

1 |-> 10 // List(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

with

import spire.math.Interval
import spire.std.int._

Interval(1, 10).iterator(1).toList // List(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
