[Haskell-cafe] Collecting examples where GHC generates unintuitive error messages

Hello all,

A discussion of GHC and error messages came up on ghc-devs. I'd like to
give back to the community and try to improve this part of GHC. So, I
created a repo to collect error messages (
https://github.com/bollu/hask-error-messages-catalog). That way, there's
some concrete context for anyone who's working on the error messages
subsystem of GHC.

Elm does this as well (https://github.com/elm-lang/error-message-catalog),
though they catalogue *all* errors.

I'd be grateful for short examples where GHC generates unintuitive error
messages, and perhaps a short explanation of what *would* be useful if
possible. If you do have certain examples, please either open a pull
request against the repository, or post a snippet on the mailing list.

Thanks for the help,
Sending this from my phone, please excuse any typos!
