Re: [Haskell-cafe] Transactional memory going mainstream with Intel Haswell

It seems like it would still be useful for *optimizing* the implementation of STM in Haskell; in particular, small transactions seem like a great way to implement lock-free data structures by handling the non-composability of compare-and-swap. So while you wouldn't implement "atomically a" by "XBEGIN; a; XEND", you might implement atomically by doing the transaction log as we do now, then using XBEGIN/XEND around the commit operation. -- ryan On Thu, Feb 9, 2012 at 11:12 AM, Austin Seipp wrote:

would any haskell STM expert care to comment on the possibilities of
