Yes, but are there any effects systems in use outside of maybe Haskell? Effects seem mostly to be stuck in the research lab and have been for a long time.

- hayley-patton 3y agoI don't mean "effects" in the sense where you can have effect handlers which get delimited continuations and all; it'd just mark what could happen (like checked exceptions). But I can't think of any languages with that and not effect handlers; Koka, Eff, and Unison come to mind for effects, though their practical-ness may vary.
- zozbot234 3y agoDo you really need effect handlers as a separate feature once you have async/await? It seems like you could easily encode one with the other.
- hayley-patton 3y agoAn effect handler is allowed to invoke a continuation multiple times; I believe this is not possible with async/await.
- ohgodplsno 3y agoVerse has effects, which by virtue of exposing it to the entire Fortnite community probably makes it a bigger language than Haskell in terms of user counts. https://dev.epicgames.com/documentation/en-us/uefn/specifiers-and-attributes-in-verse https://dev.epicgames.com/documentation/en-us/uefn/specifier... converges/diverges, computes, varies, reads, writes, transacts, no_rollback.
