    Capture an _exception-safe_ side-effect such as memory mutation or randomness

    Capture an _exception-safe_ side-effect such as memory mutation or randomness

    Example:
    1. import izumi.functional.bio.F
      
      val referentiallyTransparentArrayAllocation: F[Nothing, Array[Byte]] = {
        F.sync(new Array(256))
      }
    Note

    If you're not completely sure that a captured block can't throw, use syncThrowable

    ,

    sync means synchronous, that is, a blocking CPU effect, as opposed to a non-blocking asynchronous effect or a long blocking I/O effect (izumi.functional.bio.BlockingIO3#syncBlocking)

  8. abstract def syncThrowable[A](effect: => A): F[Any, Throwable, A]

    Capture a side-effectful block of code that can throw exceptions
