[Haskell-cafe] Re: ANNOUNCE: HNOP 0.1

My congratulations to the development team; this is an important 
contribution to the community.

You might want to use {-# OPTIONS_GHC #-} rather than {-# OPTIONS #-}, 
unless compatibility with older versions of GHC is a goal.  Still, the 
pragma only turns on warnings, so it's harmless.

Only IO makes sense really, since by definition every non-IO expression 
does nothing, so the only interesting way to do nothing is in the IO 
monad.  I imagine this interface would be relatively stable.  I'm not 
sure at this stage where in the module hierarchy we should place it, though.
