Some definitions and exports got changed, so in 6.12 the (-> a) Monad instance is exported whereas in 6.10 it isn't.

What? From where?

I thought the whole reason the Monad ((->) a) instance was in Control.Monad.Instances (instead of Prelude) was to retain compatibility with the library report.

I forget the specifics, but we had a discussion on this in #haskell a month or so ago: IIRC either the instance definition's location was changed or else it was re-exported by Control.Monad now or something.

Are you sure? This would be a fairly significant change, and there's no mention of it in the 6.12 release notes. -- Dave Menendez http://www.eyrie.org/~zednenem/
