[darcs-devel] [issue1895] create a customised monad for Darcs to do IO in

[Jason Dagit]

Jason Dagit <aoeu> added the comment:

One thing we can do to make this easier, is to write wrapper libraries around 
the IO primitives to make them work for any MonadIO.  As a proof of concept, 
and a library to contribute to, see the monadIO package on hackage:
http://hackage.haskell.org/package/monadIO

See for example,
  newIORef :: MonadIO io => a -> io (IORef a)

Then we should be able to create a MonadIO instance for any wrapper monad that 
we choose and use these primitives instead of the standard haskell ones.
