It's not true in the case of functions that return dynamic arrays, 
strings or interfaces. Because of these types require special 
finalization and they must be initialized to nil by default. So the 
expected behavior is:
1) the result value must be nil
2) the compiler must show warning "function needs return value"

P.S. Delphi doesnt return nil and doenst show warning.
