You mean like returning tuples in other languages? Neat feature, but we 
don't have it in Sather and it would be overkill to implement it just 
for error-handling :-)

When really needed, the feature can simply be emulated by packing up 
the return type in a new class or by using out-arguments.

Anyhow: Effectively, it would just match (2), only that you would 
extend the set of possible return values. Still, the user would have to 
check after the call whether it was successful.
