It seems unlikely that there'd be any stuff that changes.

The most common situation is the following:

function someluafunc()
    somecfunc()
end

in this case, someluafunc does not actually reference the C function
somecfunc. Instead, it references the string "somecfunc", and when it
is executed it looks up the entry in the global table with that key.
So the serializer never even touches the C function somecfunc.
