That's the thing.  The function will definitely have upvalues.  How
does one access them?

It's easy if the function has no upvalues. Just use string.dump. If the
function has upvalues, you'd have to serialize them, and they might be
arbitrary objects including userdata.

You might or might not want to worry about the function environment.
I'd be inclined to not worry about it, since the remote machine is
likely to want to run the function in a sandbox anyway.
