# Here’s an example of defining an lvalue subroutine in Perl

sub my_lvalue : lvalue {
    my $value;
    return \$value; # Return a reference to the variable
}

# Usage
my $var = my_lvalue; # Get a reference
$var = 5;            # Modify the variable through the reference
print my_lvalue;    # Output: 5
