Not short circuited

If you want to do the following:

boolean pass = true;
pass = pass && test1();
pass = pass && test2();

It is NOT equivalent to the following:

boolean pass = true;
pass &= test1();
pass &= test2();

Because the &= operator is not short circuited. It compiles and works just fine for booleans, but it is a bitwise operator at heart and only works for booleans out of sympathy.

What we need is a &&= operator.
