So it is possible to define: ``` -- name: \ExampleFunction @list -- default-result: array ``` But this has 2 flaws: 1. The default return result for `@list` is always an `array` 2. This Return-Handler does not support **any** default return values The manual states clearly: > **Attenion Number 2:** The `@list` result handler does not support any default return values. Since it always returns a Generator yielding values, it can't be replaced with a scalar return value of any kind for empty result sets. So the correct behavior is to throw an exception when such a configuration error is made. Otherwise, the user will have a hard time in debugging to locate this error.
