This is one the design rule of Gambas : a method has to always return the same datatype, otherwise it must return a Variant. That way, the interpreter can optimize its code at runtime. In your example, through inheritance, the same method may return a Variant[] or a String[] for example. If you have a real example, I may tell you how to do differently.
