Hi everyone! I want to present a couple of STM data structures which were implemented by me and Ryan Yates this summer (during GSOC 2015). I decided to create only a candidate package [1]. I would be glad if anyone can take a look and/or comment on topic. Since Hackage does not provide the easy way to `cabal install` candidate packages I have written a script [2] which should do all the work for you. It create a directory in /tmp and initialized sandbox along with cloning the library from github [3]. After that it will download Haskell program with an example of data structure usage. Thank you for your attention.
