I like it as well because there's no call to status() and the concrete
types of the return variables are irrelevant to the user. (Not only
scripting languages but also C++17 finally introduces "structured
bindings" to support this form of local tuple binding.)
The key question is whether it will only be a one-off or fits more
broadly into the language as part of first-class tuple support.
