What is the difference between Perl's ( or, and ) and ( ||, && ) short-circuit operators?

Question

Which of these subroutines is not like the other?

sub or1 {
    my ($a,$b) = @_;
    return $a || $b;
}

sub or2 {
    my ($a,$b) = @_;
    $a || $b;
}

sub          


        

Answer 1

In Perl 5, "or" and "and" have lower precedence than "||" and "&&". Check out this PerlMonks thread for more info:
