Hi, I got this deprecation warning: Warning: Module `GHC.Handle' is deprecated: use GHC.IO.Handle.Base instead But I think it should have been: Warning: Module `GHC.Handle' is deprecated: use GHC.IO.Handle instead There is no GHC.IO.Handle.BAse in my installation of GHC 6.12.1. The problem (it it was not intended) is there in the current head too: ~/haskell/ghc.head/libraries/base 836> darcs what -u hunk ./GHC/Handle.hs 18 -- #hide -module GHC.Handle {-# DEPRECATED "use GHC.IO.Handle.Base instead" #-} ( +module GHC.Handle {-# DEPRECATED "use GHC.IO.Handle instead" #-} ( withHandle, withHandle', withHandle_, wantWritableHandle, wantReadableHandle, wantSeekableHandle, ~/haskell/ghc.head/libraries/base 837>
