Hi Max,

I'm not sure I follow.  You have a lot of functions in Lua, that you 
want to call from C later on, but you don't need to give them names?

function foobar()
  return {
    assert(loadfile'setup');
    assert(loadstring'return 2+3');
    function() return 4+5 end;
    function() print(whatever) end;
  }
end

So you want to call foobar from C, store the table of functions 
somewhere, then later on, call each of the functions in a loop or 
something?  Basically the following in C ?

  t = foobar()
  for n,v in t do print( v() ) end
