Dear Committee,

Back in March I recommended to accept GHC Proposal #330 "Decorate exceptions with backtrace information". It appears to me that we all agree that the proposed change is a good idea. There were a couple of technical suggestions that the author readily incorporated into the proposal text (the most important addition: nested `WhileHandling` annotations). I've skimmed the proposal one more time before writing this message and I find that it is in a very good state now.

I'm about to declare it accepted, any last moment objections?

My questions have been addressed, I'm now content with the proposal.

Out of interest, why?

I'm not sure that I can quite say. The idea of annotations being somewhat implicitly passed, the symmetry with `HasCallStack`: it appeals to me. I guess it's not a very strong preference.
