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

Both versions are short-circuiting in Perl, but the 'textual' forms ('and' and 'or') have a lower precedence than their C-style equivalents.
