The minimal megaparsec tutorial

"In my functional programming course to Master Students of Telecom Nancy, I like to use parsing as an example of monadic programming, relying on the megaparsec library. My only concern with megaparsec is that its official tutorial is long: at the time I’m writing, it’s 15000 words long." https://www.tweag.io/blog/2025-04-24-minimal-megaparsec-tutorial/
