What is this 'metatable' thing below? It is not something from standard LUA
distribution, is it?

Well, I tried this:

  > t = {}
  > metatable(t,t)
  > t.__call = function(...) print(unpack(arg)) end
  > t(1,2,3)
  table: 003FDCB0 1       2       3

In Lua 5.0 work-0 and it worked just fine. So I'd have to say that it is
definitely allowed. Opens up some interesting possibilities, doesn't it?
