Type system of Fortnite's Verse language
Tangential, and because I had to look it up:> Verse has been designed by some people who really know what they’re doing: Lennart Augustsson,
Joachim Breitner, Koen Claessen, Ranjit Jhala, Simon Peyton Jones, Olin Shivers, Tim SweeneyThe listed people are all luminaries of the functional programming world (and adjacent, like theorem proving and software verification), particularly Haskell. Hell, Simon Peyton Jones is one of the creators of Haskell.My point is, the creators of Verse aren't just a bunch of coders (pejorative) who felt like creating Yet Another Language.
