Is this possible in D?
You can wrap return type in Variant
(http://dlang.org/phobos/std_variant.html) but it is inefficient,
weakens typing and considered a bad approach in natively compiled
language. Better approach probably is to use null as an indicator
(as string[] is a reference type) or throw an exception.
