We'll move this to JavaScript eventually, see
https://github.com/dslomov-chromium/ecmascript-structured-clone for
work in progress, and at that point you'll need to make it clear it
ends up in a different global as well (realm in ES6-speak). So you
can't just use clone() as that only works same-global.
