If you import Control.OldException instead of Control.Exception then it will be identical.
But fixing old code to work with the new library is very easy (e.g. changing catch to catchAny if you get an ambiguous type variable), and as Simon pointed out, places were you actually have to make changes could do with being sanity checked anyway.
so, all libs on hackage developed for 6.8 will become obsolete again? :)))
is it equally possible to put a NewException library for hackage ghc<6.9, providing those new function names that we introduce? Would that help reduce gratuituous incompatibility, or would things still break too much, or is it just plain impossible because of module-naming and how base is fixed? :-) -Isaac
