Thanks, I have also found literste-li when I searched, but thought it didn't looked  as suggested .

I have played a bit yesterday,  for about an hour and managed to find readevalloop in lread.c in sources. I managed to get a partial hack to work in some cases, but in other I get parse errors. I am not sure I understand exactly how the parser hangs together yet, if I can do everything in that function or I have to change some of other functions too. I will have more time tonight evening.

The fact that it's written is Haskell is just incidental.

Hmm... The closest I can find is https://github.com/jingtaozf/literate-elisp/
but it doesn't quite match what I think I was referring to.
