I know the result of that looks absurd at first, but there's a reason, in fact :-)

You're looking at $first ||= $last = $_; and mentally comparing it to $first = $last = $_;

The problem is: you should compare it to $first = $first || ($last = $_)

Being a short-circuit operator, ||= doesn't get it's right-hand side to be evaluated unless necessary :-)
