    This is essentially how continuation based effect systems work, check out eveff and eff.
  • Where's more discussion of the designs of effect systems?

    Languages such as Koka only support algebraic effects, not scoping operations such as catch and listen. The Effect Handlers in Scope paper introduces scoping operations, which lead to the Haskell libraries fused-effects and polysemy, but they turned out to have some weird semantics. eff is her effort to fix that.

    While her eff is still under construction, there are relative more mature pieces like Koka etc. I'd very much like to understand how her concerns map to those other effect systems, but can't find more write-ups about the design space of effect systems.
  • Languages that don't support Error-Catching as a Control Structure?
    1 project | reddit.com/r/ProgrammingLanguages | 22 Oct 2021
    There are a few languages that have algebraic effect systems, most notably Haskell, but these systems are implemented as libraries, not baked into the language (which can have advantages and disadvantages).
  • The Problem of Effects (2020)
    5 projects | news.ycombinator.com | 27 Aug 2021
    Let me tell you what I'm worried about with effects systems: One of the smartest people I know of has a library called Eff https://github.com/hasura/eff that efficiently implements effects through some modifications to GHC. The thing is, she's pretty much stopped working on because she found some really nasty semantic edge-cases that she couldn't resolve to her satisfaction. (I don't understand the problems well enough to describe them, and I think they're specific to lazy languages, but it has left me cautious about the effect model in general.)
  • Thoughts on polysemy?
    1 project | reddit.com/r/haskell | 26 Jul 2021
    eff was supposed to solve (some of) the above problems, but it's stalled now.
  • A solid GUI Framework for Haskell?

    Why do you need a GUI library, if you can write your application using extensible effects frameworks, just choose any and enjoy!

    It means that you can see a type signature like this and you know immediately how it will provide what you want in the context of an arbitrary monad "stack." It means that when you are looking to understand how to use e.g. MegaParsec it doesn't surprise you that the discussion of the relevant monads is the first thing in the tutorial. It means you know why this exists https://hackage.haskell.org/package/scotty-0.12/docs/Web-Scotty-Trans.html and maybe you can even fumble through https://docs.servant.dev/en/stable/cookbook/hoist-server-with-context/HoistServerWithContext.html and use it in your app even if you don't otherwise understand all the type-level magic happening in Servant. You'll also understand what to do if you're faced with a type signature in IO or Maybe or whatever concrete monad and you have to integrate it with a more generalized monad. You may also start to understand why everyone is so interested in effect systems.
