GlobalLayer

Note, this should only be called when assigning the result to a global value. If not, the global cache ref will not be the same, and this does nothing.

--- good --- val res: ULayer[Int] = GlobalLayer.cacheVal { ZLayer { Random.nextInt } }

--- bad --- def res: ULayer[Int] = GlobalLayer.cacheVal { ZLayer { Random.nextInt } }

--- bad --- val res: ULayer[Int] = for { _ <- ZLayer { ZIO.logInfo("logging") } res <- GlobalLayer.cacheVal { ZLayer { Random.nextInt } } } yield res
