 * More familiar flow control handling of machines, e.g. catching and wrapping thrown exceptions.
 * Explicit stage denotion in the invoice machine?
 * __Submachine abstraction and payment submachine implementation__.
-* __Properly pass woody contexts around__.
 * __Invoice access control__.
+* __Proper behaviours around machines w/ internal datastructures marshalling, event sources and dispatching.__
 
 # Tests
 
-* Fix excess `localhost` definitions (as soon as service discovery strategy will be finalized, hopefully).
 * __Add generic albeit more complex test suite which covers as many state transitions with expected effects as possible__.
-* Employ macros to minimize pattern matching boilerplate.
