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 . I think the approach is viable and perhaps even
straightforward. I have the sketch of an implementation here .
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.
