TRICK
test & operator = (const test&) { ... }
This is the standard way to overload assignment operator in c++ by reference.
Then, t1 = t2 = t3 (t1, t2 and t3 are instances of class test ) calls above assignement operator twice.
in other hand, returning void will prevent users from 'assignment chaining' i.e t1 = t2 = t3.
