- def respond(k: (Try[R]) => Unit): Try[R]
Invokes the given closure when the value is available.
Invokes the given closure when the value is available. Returns another 'This[R]' that is guaranteed to be available only *after* 'k' has run. This enables the enforcement of invocation ordering.

- def throwable: Throwable
Returns the throwable if this is a Throw, else raises IllegalStateException.
Returns the throwable if this is a Throw, else raises IllegalStateException.
Callers should consult isThrow() prior to calling this method to determine whether or not this is a Throw.
This method is intended for Java compatibility. Scala consumers are encouraged to pattern match for Throw(t).
- def toOption: Option[R]
Returns None if this is a Throw or a Some containing the value if this is a Return
Returns None if this is a Throw or a Some containing the value if this is a Return

- def transform[R2](f: (Try[R]) => Try[R2]): Try[R2]
Invokes the given transformation when the value is available, returning the transformed value.
Invokes the given transformation when the value is available, returning the transformed value. This method is like a combination of flatMap and rescue. This method is typically used for more imperative control-flow than flatMap/rescue which often exploits the Null Object Pattern.
