How to use Using.Manager with Scala 3 given

[AugustNagro]

In Scala 2, it's common to write

import scala.util.Using

Using.Manager { implicit use =>
  runProgram()
}

def runProgram()(implicit use: Using.Manager): Unit =
  println("hello world")

How can we convert this to Scala 3?

Can you provide a complete piece of code that compiles in Scala 2?

Sorry, edited :)

[bishabosha]

inline def managed[T](inline op: Using.Manager ?=> T): Try[T] =
  Using.Manager(op(using _))

managed:
  runProgram()

[AugustNagro]

That's great, although it would be ideal if users could write something like

Using.Manager { given use =>
  runProgram()
}

Directly. Or maybe def managed could be added to the StdLib eventually.

[som-snytt]

Using.Manager { case given Using.Manager => runProgram() }

@som-snytt very nice
