   This has been a pretty frequent source of feedback, and while I had ideas on that in my head, clearly I did not communicate them well enough

   I updated the website & README with more of a rationale/viewpoint of why Aria exists. Please take another look: https://github.com/egranata/aria/blob/master/README.md

    Project mention: Writing more readable parsers in Haskell using keep and skip from elm/parser | dev.to | 2026-04-16

    The CPS transformer from Chapter 6 of EOPL3 reuses the LETREC language from Chapter 3 with the addition of multiargument procedures and multideclaration letrec expressions. I already wrote a parser for it when I solved exercise 3.33 so I decided to start writing my implementation of the CPS transformer by basing my implementation on LETREC-3.33.
