“In other languages, it would be considered overkill to write a full parser when a simple regex can do the same thing. In Haskell, writing a parser is no big deal. We just do it and move on with our lives.”

I see a long code file filled with comments and long paragraph-level explanations. I think I’d rather just learn and use regex.

I mean that's the nature of article code no? You are writing for a generic audience and want to be very explicit as to what your code is doing to teach the audience.

For your average haskell programmer you could drop all of those comments since the code isn't really doing anything that couldn't be determined by just reading it.
