Strong accept from me. I left one question about the backtrace collection defaults on GitHub. On Mon, Mar 6, 2023, at 08:44, Vladislav Zavialov wrote:
Dear Committee,
Ben Gamari has proposed #330 "Decorate exceptions with backtrace information". Read it here:
https://github.com/bgamari/ghc-proposals/blob/stacktraces/proposals/0000-exc...
The proposal attaches contextual information to thrown exceptions. This information includes (but is not limited to) backtraces, making it possible to debug uncaught exceptions more effectively.
This is a very nuanced change, since it modifies SomeException, throw, catch, and other exception-related definitions whose use is extremely widespread. We might end up affecting our users in unexpected ways. Because of that, I ask the committee to review the proposal with the appropriate amount of care.
I am recommending acceptance because adding observability to our programs is an important part of developer ergonomics. From the proposal discussion, I have got the impression that there are numerous commercial users who would benefit from this.
Please take a look at the proposal text and share your thoughts either here or directly on GitHub.
