I collect additions to the FFI on the Haskell' wiki:
http://hackage.haskell.org/trac/haskell-prime/wiki/ForeignFunctionInterface
I added a note about these types. Any other ISO C types that we should
include?

Greetings!
I'll try to update the Haskell community periodically on the status of
the Haskell' language standard.
As mentioned previously, we are currently focusing on two topics,
concurrency and the class system. If you feel that you have anything
important to contribute to those topics, now is the time to review the
proposals, join in the Haskell' mailing list and let us know what you
know!
Stephanie Weirich has posted a summary of the class system discussion
here:
http://hackage.haskell.org/trac/haskell-prime/wiki/ClassSystem
Stephanie says:
This page is important because it lists all of the proposals not
related to MPTCs as well as trying to capture the big picture
about where we stand with respect to MPTCs. I've been trying to
not duplicate text that appears elsewhere in the wiki, but just
provide a consistent picture of the state of the discussions on
the mailing list.
Please take a look at this page and help me fill it out. In
particular, 've been trying to take a pulse of where we stand on
some of these issues, and some of you may not agree! Tell me if
I'm off the wall. Also, I've (mostly) concentrated on issues that
have tickets, so I may have missed some issues that were only
discussed in the mailing list. Please let me know if there is
anything I've forgotten.
Simon Marlow has posted a summary of the concurrency discussion here:
http://hackage.haskell.org/trac/haskell-prime/wiki/Concurrency
Simon says:
I have tried to summarise the various points that have arisen
during the discussion. If anyone feels they have been
mis-paraphrased, or I have forgotten something, please feel free
to edit, or send me some text for inclusion. I don't want to
include long gobs of text in here, though: just summarise the
main points, and if necessary link to relevant mailing list
posts.
Thanks, Simon & Stephanie for keeping things moving forward!
peace,
isaac
