If you look at the stability tag of ghc libraries you will see that a lot of them are marked as "provisional" (Network.URI for example) or "experimental" (Control.Monad.Trans).
This may not refer to what most people care about; the "experimental" stability of Control.Monad.Trans is related to its use of fundeps and undecidable instances, and the possibility (likelihood?) of its being switched to type families (which "shouldn't" change its user-visible interface, as I understand it). -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
