Ha great!

When is the "forthcoming" release expected?

Thanks for all the work on NHC btw. My morrow compiler
can be compiled completely with it (~20.000 lines of Haskell)
and it works great (except for the lack of readline functionality)

All the best,
  Daan Leijen.

on the side:
I believe it is quite important for the Haskell community
to have another "real" compiler than GHC available or otherwise
Haskell will in the future be defined as `what is accepted by ghc'.
I hope you can keep up with making the standard ghc libraries
available with nhc98 as this is probably one of the most important
issues for "real" programs.  (and yes, getting wxHaskell compiled
with nhc98 is a goal for me -- although it will probably be restricted
to the wxcore layer as nhc98 is too strict on instance head forms)
