Comment(by augustss):
First, I don't really mind if ghc is not backwards compatible.
A compiler has to move forwards and can't support old things forever.
I just want to point out that every new ghc release is a pain for people
with a large code base.
Here are the things that caused pains in porting:
* haskell98 no longer supported
* change of type names in Typeable (that took quite a while to debug)
* Prelude.catch deprecated (we compile with -Werror)
* network package didn't build using Setup.hs (as usual)
* glib package didn't build for reasons I never figured out
