Running hlint is always useful. e.g. it will spot redundant brackets:
p.hs:35:40: Suggestion: Redundant bracket
Found:
(length xs) - 1
Why not:
length xs - 1
and unidiomatic expressions like
p.hs:54:10: Warning: Use concatMap
Found:
concat . map (make8 . int2bin . ord)
Why not:
concatMap (make8 . int2bin . ord)

Sure. I remember old days Tcl/Tk utility "expect" for such interactive
scripting sessions. Open a pipes and communicate with process :) Today
there are tools similar to "expect" for scripting command line utilities.
Also Emacs works with GHCi (interro) in such way. Also Dante IMHO.
Visual Studio Code Haskelly and Haskerro, etc..

Actually, I dont know if I have asked good question to what I need.
So, I would like to run the process:
stack ghc -- --interactive -XOverloadedStrings
and then, somehow from 'outside' push string commands to it...

You should be able to run something like this:
echo 'putStrLn "hi"' | stack exec -- ghci -XOverloadedStrings
