Effectful

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!
