if you put the function in table (like this):
local t = {
  fn = h;
};
it should write out the thing correctly.

there can be issues with code (it taken from the live and complex
program), but nothing an average Lua programmer can't fix. i really can
miss something, but not anything crucial.

i'd like to hear any bugreports though. if it works, somebody can put
it in the wiki, i think (i'm toooooo lazy to do it myself for now, and
i'm not sure it works ok, so please, test it).
