Yes. I’m divided into “hum… 100 lines is larger than I expected” and “what did he mean ‘from scratch’? did he write the parser combinators? if so, 100 lines is crazy small!”
But I’m settling in believing 80 of those lines are verbose type declarations.

With recursive list comprehensions you can cram quite some complexity into one line of code.
You could probably write a very basic parser combinator library, enough to parse JSON, in 100 lines of Haskell
Judging by the Parser newtype, he did.
