I agree with Bryan, +1 for fast-tracking this into the platform. (Which is to say, we heavily review and test the proposal over the next few months rather than waiting for it to become established before incorporating it into the platform.)

My only concern is that it hasn't seen any use yet, so this is an unusual way to be doing things. If you were submitting this proposal 6 months from now, it would be a no-brainer. That being said, I infer that the motivation behind getting it in this year is to be able to point people at it and say "just use this, it's in the default distribution". Which I think is quite sensible. I'm in favour of this going in. I like the API, the documentation is good, and the code is clean.

I am making a formal proposal to have the async package included in the Haskell Platform:

  http://trac.haskell.org/haskell-platform/wiki/Proposals/async

See the wiki paage for details, and a list of open issues for discussion.

I just uploaded the async package itself to Hackage:

  http://hackage.haskell.org/package/async-2.0.0.0

documentation isn't there yet, so I've uploaded it here:

  http://community.haskell.org/~simonmar/async/

I have set the deadline to 13 August 2012 (2 months' time), with comments due by 13 July 2012 (one month).  There's plenty of time before the next platform release anyway (scheduled for 12 November 2012).

-0.

AFAIUI the HP is for battle-tested code and libraries where you can just say "here, use this!" IMO async doesn't pass this test since it hasn't seen any real use yet.

sounds like a challenge for us all to battle-test it over the next month :) Conrad.

So my thinking here is that

- similar APIs already exist on Hackage, so it's not completely new (and that also demonstrates demand)

- the code is mostly very simple, it's hard to go wrong.

But if people feel we should wait a while, that's fine by me.

I think the fact that we're seeing so many proposals is suggestive; it's easier to deal with those before it lands in the Platform, if nothing else. -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms

Hi Simon,

Nice package!

For completeness sake, shouldn't the package also offer these functions:

* asyncOS * asyncOn * asyncWithUnmask * asyncOnWithUnmask

analogous to the same functions in Control.Concurrent.

I don't know if they will be used a lot but I also added them to the threads package:

Simon, I've send you a pull request to add these: https://github.com/simonmar/async/pull/2 Cheers, Bas
