A discussion of the Haskell type system is not what I expected when clicking that link.
Kindness may be referring to higher kinded types and for mean girls probably just forced lingo to refer to people who don't take kindly to functional programming and types.
(I never even considered "this is HN so it's probably tech-related". Don't know what that says about me or the site!)
But I am actually glad it's about Haskell, I am a gonna read it now (and it's refreshing to see it being written by woman).
I don't mind the movie references, I don't think it's sexist. (Quite the opposite, I think standard mathematical writing is too dry and benefits from having an unrelated theme to add a bit of spice.)
Current reality is hard for everyone. When men behave like men, some women complain, when women behave like women, some men complain, it's really hard to please everyone. Take it easy, everyone.
Oh My God, neals! you can't just ask people what their first thought was...
