A couple of days ago, I gave a talk at Boston Haskell about a shiny new speculative evaluation library, speculation on hackage, that I have implemented in Haskell. The implementation is based on the material presented as "Safe Programmable Speculative Parallelism" by Prakash Prabhu, G Ramalingam, and Kapil Vaswani at last month's PLDI.

I've uploaded a copy of my slides here:
