Can I use a tactics under `coqtop -nois`?

Just like op of other question, I am redeveloping Coq.Init.Prelude under -nois for pratice.
I want to use tactics, but they are not working.

I tried Declare ML Module "ltac_plugin". but it didn't help.

Welcome to Coq v8.8 (eccf1d50b020e87b4d19d0bda43361e1e82d01b1)

Coq < Declare ML Module "ltac_plugin".
[Loading ML file ltac_plugin.cmxs ... done]

Coq < Goal forall A:Prop, forall proof:A, A.
1 subgoal

  ============================
  forall (A : Prop) (_ : A), A

Unnamed_thm < intro.
Toplevel input, characters 0-5:
> intro.
> ^^^^^
Error: Syntax error: illegal begin of vernac.

You also need to Set Default Proof Mode "Classic" to have access to the standard tactics. This option is currently undocumented.
