Is there a good practice to serialize/de-serialize boxed_value? #596

Hi,

Just like the title. I was wondering if there is a good practice to serialize/de-serialize boxed_value?

In my usage scenario, two chaiscript execution ends are connected by bytearray stream, so it would probably be convenient and efficient if boxed_value could be serialized directly. But after thinking about it for a while, there doesn't seem to be a good way to do it?

Thanks.
