Hi everyone.
I am working on a proposal for some additions to the base library and some
modifications to GHC in the same style as the do notation support for
Applicatives. It is still very much a work in progress, but any
input/constructive criticism would be greatly appreciated; this is the

Hi Sophie,
In your proposal draft, I am missing the rationale part.
Yeah, I'm still writing it - I definitely need to expand that a bit mor.
Do we need *all* of these classes in base in order to desugar proc? Can
you demonstrate why they are needed? Or will something simpler suffice?

C-- was originally envisaged as a target language for a variety of compilers.
But in fact LLVM, which was developed at a similar time, won that race and
has built a far larger ecosystem. That's fine with us -- it's great how
successful LLVM has been -- but it means that C-- is now

I’m guessing that the primary audience for your proposal is the Core Libraries
Committee, rather than GHC itself. I’m cc’ing them.
So far as GHC is concerned, there is a long-running ticket #7828 that your
proposal may bear on. I am not satisfied with GHC’s treatment of arrows; it is
Is there a Trac ticket too?

It is that time again where once every 6 months, we write our entry

what exactly we're all doing.
I say 'we' write this of course because I need everyone to write some
stuff on what they're doing. :) I'll editorialize it

Dear Simon,
No, there is not. Should every patch in Phab, have an associated ticket as well?

Hi,
At ICFP Simon Peyton Jones encouraged me to compile GHC on Windows. I
did so in the past about 5 years ago, and it was a painful experience.

Hello SPJ (cc Neil Mitchell),
on IRC it was brought up that there will be someone at GHC headquarters
working on a Shake based build system. Can you tell us a little bit more
about these plans.
I wanted to try implementing this as well, but am happy to work on
something else.
Kind regards,
In ghc 7.8.3 on the Mac, for some packages cabal reinstalls the package
