Currently the following 32 library packages directly depending on mtl are broken by the changes (including reasons and number of packages that directly or indirectly depend on these):
happstack-server-0.5.0.2 Functor constraint (32 clients)
I intend to upload a new version of happstack 0.5 which has the proper constraints. And happstack 6 will be migrated to transformers/monads-fd. Not sure about the other 31 packages :p I am somewhat reluctant to follow the PVP, but it is also a pain when packages specify constraints, and then never update them when newer compatible versions come out. In part because there is no notification that an update is available. Though, I am hoping to use http://packdeps.haskellers.com/ to solve this for the packages I maintain. - jeremy
