def onExit[S, P[_]](finalizer: IO[Unit])(implicit arg0: MonadIO[P]): RegionT[S, P, FinalizerHandle[[γ$0$]RegionT[S, P, γ$0$]]]

Register a finalizer in the current region.
Register a finalizer in the current region. When the region terminates, all registered finalizers will be performed if they're not duplicated to a parent region.
def put[A](a: A)(implicit S: Show[A]): IO[Unit]
def putChar(c: Char): IO[Unit]

Writes a character to standard output.
def putLn[A](a: A)(implicit S: Show[A]): IO[Unit]
def putStr(s: String): IO[Unit]

Writes a string to standard output.
def putStrLn(s: String): IO[Unit]

Writes a string to standard output, followed by a newline.
def readLn: IO[String]

Reads a line of standard input.
def runRegionT[P[_], A](r: Forall[[α$2$]RegionT[α$2$, P, A]])(implicit arg0: MonadControlIO[P]): P[A]

Execute a region inside its parent region P.
Execute a region inside its parent region P. All resources which have been opened in the given region and which haven't been duplicated using "dup", will be closed on exit from this function whether by normal termination or by raising an exception. Also all resources which have been duplicated to this region from a child region are closed on exit if they haven't been duplicated themselves. The Forall quantifier prevents resources from being returned by this function.
