>From the std.conv.parse() unittests:

    // @@@BUG@@@ the size of China
        // foreach (i; 2..37)
        // {
        //      assert(parse!int("0",i) == 0);
        //      assert(parse!int("1",i) == 1);
        //      assert(parse!byte("10",i) == i);
        // }
        foreach (i; 2..37)
        {
            string s = "0";
                assert(parse!int(s,i) == 0);
            s = "1";
                assert(parse!int(s,i) == 1);
            s = "10";
                assert(parse!byte(s,i) == i);
        }
    // Same @@@BUG@@@ as above
        //assert(parse!int("0011001101101", 2) == 0b0011001101101);
        // assert(parse!int("765",8) == 0765);
        // assert(parse!int("fCDe",16) == 0xfcde);
    auto s = "0011001101101";
        assert(parse!int(s, 2) == 0b0011001101101);
    s = "765";
        assert(parse!int(s, 8) == octal!765);
    s = "fCDe";
        assert(parse!int(s, 16) == 0xfcde);

This is caused by `parse()` using pass-by-ref for the first argument, which
does not support rvalues since `scope ref` isn't implemented yet.
