Welcome to Haskell'


The Haskell programming language is more-or-less divided into two "branches". The Haskell 98 standard is the "stable" branch of the language, and that has been a big success. A lot of progress has been made over the last few years in the "research" branch of the Haskell language. It is constantly advancing, and we feel that it is time for a new standard which reflects those advancements.

Haskell' (pronounced "Haskell Prime") will be a relatively conservative refinement of Haskell 98. It will be the work of this committee to adopt a set of language extensions and modifications and to standardize a new set of libraries. We maintain a set of Principles to help guide our choices.


These are the resources that the community and committee are using during development of Haskell'.

  • The haskell-prime mailing list: all technical discussion will take place here, or (if other meetings take place) be reported here. Anyone can subscribe, and any subscriber can post questions and comments, and participate in discussions. Anyone can read the list archives.
  • This wiki: to document consensus. This system is publicly readable, but only committee writable so that we may present it as the "official" output of the committee. If you ever feel that the wiki is not accurate as to the consensus, please alert the committee! See WikiGuidelines.
  • The haskell-prime code repository: a darcs repository for experiments, proposed libraries,and complex examples. darcs is a decentralized system, so anyone can use it, but patches should be sent to Isaac Jones.


(March 2008) After a quiet 12 months or so, we are gathering momentum again, and the committee is beginning to make concrete decisions. To see what has been decided, keep an eye on the Status page.

To help make the process more agile, we are no longer using tickets to manage issues. Instead, the list of current proposals is kept in the Haskell source file, from which the Status page is automatically generated. We are still using the wiki to document proposals, and we also intend to document the rationale for each decision here on the wiki.
