Comparing the Same Project in Rust, Haskell, C++, Python, Scala and OCaml

We did our compiler in Rust and my first comparison was with a team that used Haskell, which I expected to be much terser, but their compiler used similar amounts or more code for the same task. The Haskell team was composed of two of my friends who’d written maybe a couple thousand lines of Haskell each before plus reading lots of online Haskell content, and a bunch more in other similar functional languages like OCaml and Lean. I believe that someone like Edward Kmett could write the same compiler in substantially fewer lines of Haskell, in that my friend’s team didn’t use a lot of fancy super advanced abstractions, and weren’t allowed to use fancy combinator libraries like lens.
