.map breaks fresh layers

[hearnadam]

Minimized reproducer:

  class A
  class B
  val a = ZLayer {
    for {
      _ <- Console.printLine("A")
    } yield new A {}
  }
  val b = ZLayer {
    for {
      _ <- ZIO.service[A]
      _ <- Console.printLine("B")
    } yield new B {}
  }

  def run =
    {
      ZIO.service[A] *> ZIO.service[B]
    }.provide(a.fresh.map(identity), b)

Expectation:

• A layer maintains its 'freshness' regardless if an operator is invoked on it.
• Using operators such as .debug should not modify freshness of a layer

Console output:

A
B

Removing the map:

  def run =
    {
      ZIO.service[A] *> ZIO.service[B]
    }.provide(a.fresh, b)

Console output:

A
A
B
