This is a rather useful extension, and as far as I can tell it doesn't have a ticket yet:

should I create a ticket? Is there any reason it might be hard to implement?
There are a range of proposals, but none of them are implemented. Wouldn't that rule them out for Haskell'?
If it's not clear which is the right way to go, then yes I guess that does rule it out. Could you summarise the proposals? If there was a clear winner, and it was easy enough to implement, perhaps we can knock up a prototype in time. The reason being I just hit a case where this would be useful, while trying to find a nice way to express extensible exceptions. Cheers, Simon
