    Love to see you chewing through this parsing problem in Haskell, I didn’t dare use Parsec because I wasn’t confident enough.
    Why did you decide to have a strict definition of Mul !Int !Int?

      My guess is because a linter and/or HLS was suggesting it. I know HLS used to suggest making your fields strict in almost all cases. In this case I have a hunch that it slightly cuts down on memory usage because we use almost all Muls either way. So it does not need to keep the string it is parsed from in memory as part of the thunk.

      But it probably makes a small/negligible difference here.

        Yep, HLS suggested it, and I figured since I’m definitely going to be using all of the values (in part one, at least), why not?

        Normally I ignore that kind of nitpicky suggestion though.
