Perl: Simple .ini parser

I wrote a simple .ini parsing function in Perl.

my $hash_ref = parse_ini("/tmp/config.ini");
sub parse_ini {
    open (my $INI, "<", $_[0]) or return undef;

    my $ret     = {};
    my $section = "_";

    while (my $line = readline($INI)) {
        if ($line =~ /^\[(.+?)\]/) { # Section heading
            $section = $1;
        } elsif ($line =~ /^(\w.*?)\s*=\s*"?(.*?)"?\s*$/) { # Key/Value pair
            $ret->{$section}->{$1} = $2;
        }
    }

    return $ret;
}
