I think I learned an extremely important life hack today
when you want to consume information from a white paper from PL research academia and you never went through a PHD program / can't understand their greek grammars, check to see if they gave a talk on the paper instead!

This tweet is brought to you by the rage I experienced when I first read this white paper and wasn't able to properly understand it:
cs.cornell.edu/andru/papers/u
Followed by my delight when I realized there is a talk for the same research!

Oh nice, this is literally the exact challenge I've been fighting with in my own lang over the last few days. Thanks for the link!

I'm still at the stage of figuring out the exact semantics, but effects in Tao (github.com/zesterer/tao/) *should* generalise just fine to bi-directional effects. Might be a few weeks until I have something worth showing the world though.

A somewhat problematic thing is that I'm trying to implement effect handlers on top of pure universe mapping (Haskell style), and this ends up needing a few odd extensions to typical effect systems to work properly without resorting to 'dirty' stuff like Haskell's unsafePerformIO

main having type World -> World. The pure core of monadic IO. I don't want to be hiding behind impurity at some level of the language just for the sake of ease of implementation.

Ohhh. Have you seen Runners? I dunno if they would help with the dodgeyness you are talking about: math.andrej.com/2019/10/28/run
(full disclosure, have not had the time to learn them)
