After five days, the answer seems to be "No, because it is impossible."

The opposite task is easier: to automate

   mymod = {func1=func1, func2=func2, ... }

That can be done easily enough by an appropriate script that processes

   io.open(debug.getinfo(1).source:match"@(.*)"):read"*a"

provided that certain conventions are followed.
