List Assignment

 my ($x, $y, $z);
 ($x, $y, $z) = f();  # if f() returns (2, 3, 7) then it is nearly the same as $x=2; $y=3; $z=7;
 ($x, $y, $z) = f();  # if f() returns (2, 3, 7, 9), then ignore 9
 ($x, $y, $z) = f();  # if f() returns (2, 3);  then $z will be undef

A regular question on job interviews: How can we swap the values of 2 variables, let say $x and $y?
