NAME
    overloading - perl pragma to lexically control overloading

SYNOPSIS
        {
            no overloading;
            my $str = "$object"; # doesn't call stringification overload
        }

        # it's lexical, so this stringifies:
        warn "$object";

        # it can be enabled per op
        no overloading qw("");
        warn "$object";

        # and also reenabled
        use overloading;
