5.17. Your Salary is in Danger - Short-Circuit

If perl already knows the final value of a boolean expression after computing
only part of it, perl will NOT calculate the rest of the expression:

if ($my_money > 1_000_000 or $my_salary > 10_000) {
    # I can live well
}


if ($my_money > 1_000_000 or $my_salary++ > 10_000) {
    # I can live well
}
