Thanks for video. Looks like you don't need to check segment for lower bound. You get to second clause only if segment >=3.

[@TeaLeavesProgramming]

You’re right - thanks for the observation.

Regarding the documentation for `rectangle`: Haddock (the documentation tool for Haskell code) supports annotating individual arguments with documentation; and I agree that would be appropriate here

[@TeaLeavesProgramming]

Thanks for the info. This is good to know.

While in this specific case it's very obvious what those arguments are, you touched a wider issues when it comes to Haskell's libraries and modules: more often than not the documentation tends to be terse to the point of being a challenge to understand. That's my biggest gripe with the community. Great video, btw 🙂

It's a touchy subject! Most of the documentation (and software) is being written by volunteers, so I want to re-emphasize that I'm not trying to diss anyone's work. What I get concerned about isn't that the documentation isn't great (that can happen in any project) but that sometimes On The Internet I encounter people who get defensive about it (...generally not the people who wrote the documentation) and insist that it's GOOD that it's overly terse.
