Usage

Just use io-silent and make sure the last value the codeblock returns is of type IO[_], for example:

```scala mdoc:io-silent
import cats.effect._
import scala.concurrent.duration._

def go(i: Int): IO[Unit] = i match {
  case 0 => IO.unit
  case n => IO.sleep(5.millis) *> IO.println(s"tick $i") >> go(n - 1)
}

go(10)
```

Which will be executed, the output captured and rendered separately:

import cats.effect._
import scala.concurrent.duration._

def go(i: Int): IO[Unit] = i match {
  case 0 => IO.unit
  case n => IO.sleep(5.millis) *> IO.println(s"tick $i") >> go(n - 1)
}

go(10)

tick 10

tick 8

tick 6
tick 5
tick 4
tick 3
