Hi everyone, After a nice discussion on IRC about the unfortunate state of error reporting in Haskell, I felt compelled to write down some long-lingering thoughts regarding backtraces on exceptions. The result is GHC proposal #330 [1]. I think the approach is viable and perhaps even straightforward. I have the sketch of an implementation here [2]. Please have a look at the proposal and leave your comments. If there is consensus it is possible that we could have this done for 8.12. Cheers, - Ben [1] https://github.com/ghc-proposals/ghc-proposals/pull/330 [2] https://gitlab.haskell.org/ghc/ghc/-/merge_requests/3236
