Denis Blank 957d3fa375 Align the cancel behaviour of result to the one used in the unhandled exception handler ... * Introduce cancellation_result to represent a cancelled async task * Add cancellation unit tests * This doesn't allow cancellation of continuables, it is meant for treating the special state action canceled on the receiver side. Cancellation of a chain is still up to the user.		2020-04-03 22:34:08 +02:00
