Unsafe hGetContents
by Florian Weimer 23 Jan '10

23 Jan '10

Are there any plans to get rid of hGetContents and the semi-closed handle state for Haskell Prime? (I call hGetContents unsafe because it adds side effects to pattern matching, stricly speaking invalidating most of the transformations which are expected to be valid in a pure language.)

Nominations for the Haskell 2011 committee
by Simon Marlow 30 Dec '09

30 Dec '09

So that the Haskell 2011 cycle can get underway, we are soliciting nominations for new committee members. Since this is the first time we've done this, the procedure is still somewhat unsettled and things may yet change, but the current guidelines are written down here: http://hackage.haskell.org/trac/haskell-prime/wiki/Committee In particular, on the makeup of the commitee: The committee should represent each class of stakeholders with roughly equal weight. These classes are * Implementers (compiler/tool writers) * Commercial users * Non-commercial users (e.g. open source) * Academic users (using Haskell in research) * Teachers * Authors In addition, members of the committee should be long-standing users with a deep knowledge of Haskell, and preferably with experience of language design. The committee should contain at least some members with a comprehensive knowledge of the dark corners of the Haskell language design, who can offer perspective and rationale for existing choices and comment on the ramifications of making different choices. To nominate someone (which may be yourself), send a message to haskell-prime(a)haskell.org. Please give reasons for your nomination. The current committee will appoint new commitee members and editors starting in the new year, so the deadline for nominations is 31 December 2009. During discussion amongst the current commitee, we realised that the choice of committee should be informed not just by the criteria above, but also by the particular proposals that are expected to be under consideration during this cycle. With that in mind, we plan that following the nominations the current committee will choose a "core commitee" of up to 10 members, and further members may be appointed during the year based on expertise needed to consider particular proposals. Accordingly, now would be a good time to start discussing which proposals should be considered in the Haskell 2011 timeframe, as that may affect the choice of commitee members. More details on the current Haskell Prime process are here: http://hackage.haskell.org/trac/haskell-prime/wiki/Process Cheers, Simon

nomination for Haskell 2011
by S. Doaitse Swierstra 23 Dec '09

23 Dec '09

Herewith I propose Atze Dijkstra as a member of the Haskell 2011 committee. Atze is the main architect/implementor of the Utrecht Haskell Compiler (see http://www.cs.uu.nl/wiki/UHC, and last year Haskell Symposium), and has as a result of that a very good insight in the implementation issues involved with new features/extensions/changes. He furthermore co-supervises Arie Middelkoop who is working on the Ruler system, which aims to be a tool for describing (the implementations of) type systems, and Jeroen Fokker who is working on a Grin-based whole- program analysis The compiler itself is currently about 100.000 lines of Haskell. A second release is planned for the beginning of next year, which will contain a completely new garbage collector, a cabal based installation scheme, and the beginning of some global optimisations. I think Atze primarily covers the following categories: Implementors, Academic users, Teachers. If you have any questions I am more than willing to answer them, Doaitse

What about using export keyword to mark the exporting functions?
