Looks like bug with return value of Proxy.new

gistfile1.txt

sub triple() is rw {
    my $storage = 0;
    my $p = Proxy.new(
        FETCH => method ()     { $storage },
        STORE => method ($new) { $storage = 3 * $new }
    );
    say $p.perl; #the output here is probably a bug
    $p;
}

my $tripled := triple();
$tripled = 4;
say $tripled;
