Hello, I'd like to bring to your attention a discussion that I have started over at Haskell-cafe [1]. I was complaining about the silent overflow of parsers for bounded integers: > read "298" :: Word8 42 I find this unsatisfying, and I have demonstrated a solution [2] that seems correct and performant. To avoid cross posting, I'd rather point you to the discussion on the Haskell-cafe mailing list [1]. I would like to help get this into GHC and also other parsing libraries. Not all libraries suffer from this issue, but some do, including GHC and its `base` package. How can I attempt this? Should I file a bug report? Or try to follow the instructions at ghc.dev [3] and submit a pull request? I would start tinkering at [this point][4] as soon as I manage to compile GHC. Would you want to share any advice beforehand? I'd really appreciate to be stopped before wasting effort ;-) Also, I probably only can work on this on weekends.
