Xojo can return arrays from method calls like

Function foo() as String()

Now what happens if you leave such a function without a return statement ?
Xojo will happily return a NIL array – not one that has no members but one that IS NIL

For instance, if you create the function as

Function foo() as string()
End Function

and then call it later like

dim arr() as string = foo
break

dim arr() as string = foo
arr.append
