STM is just additional instrument, you can completely avoid it (as we had do until 6.4 release). Below is a list of papers related to imperative programming in Haskell. first contains pragmatic introduction in this world, including all concurrency stuffs, second is about an real high-concurrency application designed by GHC team. other papers is of more theoretical (and more strict) character Tackling the awkward squad: monadic input/output, concurrency, exceptions, and foreign-language calls in Haskell [http://research.microsoft.com/Users/simonpj/papers/marktoberdorf/marktoberdo...] Writing High-Performance Server Applications in Haskell, Case Study: A Haskell Web Server, [http://www.haskell.org/~simonmar/papers/web-server.ps.gz] [http://www.haskell.org/ghc/docs/papers/concurrent-haskell.ps.gz] [http://www.haskell.org/~simonmar/papers/conc-ffi.pdf] The Concurrent Haskell Foreign Function Interface [http://www.haskell.org/ghc/docs/papers/threads.ps.gz] Asynchronous Exceptions in Haskell [http://www.haskell.org/~simonmar/papers/async.ps.gz] [http://research.microsoft.com/~simonpj/papers/stm/stm.pdf] [http://www.haskell.org/ghc/docs/papers/except_ps.gz] Imperative Functional Programming [http://www.haskell.org/ghc/docs/papers/imperative.ps.gz] -- Best regards, Bulat mailto:bulatz@HotPOP.com
