--- Comment #1 from Dennis <dkorpel at live.nl> ---
Possible solutions:
- disallow `return` on variadic array arguments
- strip `return` on variadic array arguments, making it a no-op
- allocate the array with the GC on the call site when `return` is present

Not sure which is best, I'm leaning towards the first.
