Thank you for the hint! So, if I got it correctly, since it is "impossible" to copy the whole resource around (you can't just copy a virtual machine!), a right strategy would be to use internal reference counting as an unowned ref type (as described in [https://nim-lang.org/docs/destructors.html#owned-refs](https://nim-lang.org/docs/destructors.html#owned-refs) ) ?
Or is this something like this supported already in nim?
