EffectsImplementing Algebraic Effects in CImplementing Algebraic Effects in C by Daan Leijen:
Another great paper by Daan Leijen, this time on a C library with immediate practical applications at Microsoft. The applicability is much wider though, since it's an ordinary C library for defining and using arbitrary algebraic effects. It looks pretty usable and is faster and more general than most of the C coroutine libraries that already exist. It's a nice addition to your toolbox for creating language runtimes in C, particularly since it provides a unified, structured way of creating and handling a variety of sophisticated language behaviours, like async/await, in ordinary C with good performance. There has been considerable discussion here of C and lowlevel languages with green threads, coroutines and so on, so hopefully others will find this useful!

No value restriction is needed for algebraic effects and handlersNo value restriction is needed for algebraic effects and handlers, by Ohad Kammar and Matija Pretnar:
Looks like a nice integration of algebraic effects with simple HindlyMilner, but which yields some unintuitive conclusions. At least I certainly found the possibility of supporting dynamically scoped state but not reference cells surprising! It highlights the need for some future work to support true reference cells, namely a polymorphic type and effect system to generate fresh instances.

Programming with Algebraic Effects and HandlersProgramming with Algebraic Effects and Handlers. Andrej Bauer and Matija Pretnar, arXiv preprint.
Eff has been discussed here before, and it's nice to see some more progress and a much more complete introduction. The paper is intended for a general audience (well, a general audience of PL enthusiasts). It's quite clear and contains a wealth of examples.

Eff  Language of the FutureThis is just a series of blog posts so far, as far as I can tell. But Andrej Bauer's work has been mentioned here many times, I am finding these posts extremely interesting, and I'm sure I will not be alone. So without further ado... Programming With Effects. Andrej Bauer and Matija Pretnar.
