Hi, Virgil.

Did you try this code? I think it is what you might be looking for, 
actually. Although you can do it with unpack() etc.
Or did I blow it somewhere?

static int l_docurry(lua_State *L) {
  int n = lua_pushupvalues(L);
      // lua_rotate would be useful here. Oh, well.
  for (; n > 0; --n) lua_insert(L, 1);
  lua_call(L, lua_gettop(L) - 1, LUA_MULTRET);
  return lua_gettop(L);

// Register this one as curry

static int luaB_curry(lua_State *L) {
  lua_pushcclosure(L, l_docurry, lua_gettop(L));
  return 1;

Then you can just write:
  curry(method, self)
  curry(method, self, 7)
