HP 2012.4.0.0 -- Call for Proposals

[Simon Marlow]

There's also a proposal (by me) to include the async package:

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

The deadlines have now expired.  During the discussion several people 
were positive about the package, however I don't think anyone expressed 
an opinion specifically on whether the package should be in the 
platform.  I'm not sure how to interpret that result - at the least, it 
suggests a certain lack of enthusiasm.

I'm still keen to see the package go in, mainly because when you start 
doing concurrent programming you quite quickly run into the need for 
some way to return results from threads, and then you need error 
handling.  Then you start to need a way to wait for results from 
multiple threads with error handling... people build these things 
themselves, but in fact it's quite tricky with the basic 
Control.Concurrent API to do it right.  The async package provides a 
well though-out API for that essential functionality, in a way that 
composes nicely.  It's a very small package, but it should be a part of 
our standard vocabulary in my opinion.

We should have it if only for the cool one-liners you can write with

mapConcurrently :: Traversable t => (a -> IO b) -> t a -> IO (t b)

:-)

On the other hand, given that nobody else argued for it to be in the 
platform, a reasonable decision would be "wait and see"; I'd be fine 
with that too.

Cheers,
	Simon
