One thing that bugs me about Haskell is that exceptions are not extensible.
I don't know how to craft a good solution, but perhaps if I explain the problem well, someone would come up with one.
Open datatypes would be the best solution, I think. http://www.informatik.uni-bonn.de/~loeh/OpenDatatypes.pdf
I don't think we need more extensions to do a reasonable job of extensible exceptions: http://www.haskell.org/~simonmar/papers/ext-exceptions.pdf Cheers, Simon
