Paweł Szulc

Thoughts to code compiler

Haskell developer by day, Haskell developer by night. Explorer of the uncharted territories. Father, husband, cats herder.

In this 20 minutes presentation, Pawel will introduce us to a brand new library called Effectful. It is in fact yet another effects library in Haskell, but potentially one that may finally win the "effects war".

Effectful comes with nice ergonomics - similar to what we would find in Polysemy. At the same time, Effectful is blazing fast - internally under the hood, it is implementing the ReaderT pattern.  

Can we have the best of two worlds? Polysemy-like interface with minimal abstraction costs similar to ReaderT pattern? You will have to join the talk to find out!
