Well, there is no string.concat :). [I know you meant table.concat.]

Off-topic: wouldn't it be nice if we had a string.concat that just did
(without some sanity checks and maybe luaL_tostring):

int string_concat (lua_State *L)
{
  lua_concat(L, lua_gettop(L));
  return 1;
}

Sure would make it easier to concat a dynamic number of strings
without using an intermediate table.
