Sorry JB, but `typealias` looks useless :disappointed: 

* `typealias UserId = String` allows me call all `String` functions on `UserId`
* Extension properties and functions for typealiases available on original type

Would be great if `typealias` will be converted to original type only at last step — bytecode emission and will be treat as a separate virtual type before that, preventing things mentioned above ^ as compilation errors.
