error-messages VS tech-proposals

The GHC issue tracker or the error message improvement repo are two such places to get clarification (and potentially improve the message even if it turns out to be technically correct).

Indeed there is a ticket and the error message is somewhat better in 9.4 although it still doesn't mention the guard.

Note that the Num literal issue is tracked here and there seems to be a good suggestion to fix it: https://github.com/haskell/error-messages/issues/5#issuecomment-1040788806

I think it would be great to post this over at https://github.com/haskell/error-messages too so that we can track it more easily than here on Reddit.

Also, reminder that https://github.com/haskell/error-messages exists to track these kind of issues. Feel free to open an issue there.

If you are able to articulate what aspects of the error messages you find hard to understand, please do open an issue on https://github.com/haskell/error-messages. (Or reply here then I can open an issue for you if you don't have a github account.) It doesn't have to be a concrete suggestion for improvement, even just knowing which messages are bad can be useful.

Do you know about https://github.com/haskell/error-messages

The error message is at the least very unhelpful. Please report it on https://github.com/haskell/error-messages/issues/new

Please do open an issue at https://github.com/haskell/error-messages. The issue itself can be as simple as just summarizing what you wrote here, it doesn't have to immediately suggest a good alternative. That issue tracker is in the first place intended to document all error messages that Haskellers struggle with.

Do check out https://github.com/haskell/error-messages. We have a related discussion here: https://github.com/haskell/error-messages/issues/5, but I think perhaps a separate issue for this case would be good to have.

As far as I know there is no such thing yet. The first step would be to actually collect the vulnerabilities in a central repository. The Haskell foundation has been working on such a repository, but I don't know the current status.

The Haskell foundation is working on An Advisory Repository for Haskell. That proposal also lists the necessary steps to get Dependabot support.

One body that is in a position to coordinate such funding efforts is the Haskell Foundation. Some relevant discussion is happening at https://github.com/haskellfoundation/tech-proposals/pull/27. If your work is willing to contribute funding then perhaps it would be beneficial to nudging it along if you chimed in and said so.
