Novel focus on choreographic programming
From 2 comments
I love the ambition and the fact that this is not just another "state of the art in 2015" language like I see so often. It's trying to do something genuinely different. The field…
jerf on HNI like the ideas a lot. The Readme needs some polish (I think it’s great that it reads as hand-written; an LLM could make suggestions that make it just 10% easier to read). Is…

Clean, conservative syntax
From 1 comment
First of all, the syntax is very generic and conservative. I’m extremely positive about that. It just looks like C or Typescript or Java to me and I don’t see mysterious…

Objections
Documentation does not explain choreography or show examples
From 3 comments
Your README and docs don’t describe any of the interesting or unique things here. You cover `if` in README but not choreographic programming or perceus. Did i miss some big link?…
jitl on HNI skimmed so I may have missed it, but nowhere in the README do I actually see a description of what "choreographic programming" is, or an example of it.
adastra22 on HNThe tests I could find for ‘choreographed programming’ were 1-2 lines long and demonstrated absolutely nothing, certainly nothing as elaborate as the research text is stating.…

Perceus with linear resource rule seems contradictory; cycles may leak
From 1 comment
The pitch is "one ownership rule for memory, threads, and networks," but I think there are two rules in here and they pull against each other. The resource rule as stated is…

Timeout and external call handling unclear
From 1 comment
Congratulations your language is trying to solve an hard problem. But .. your language mostly hide when you're doing an 'inside' function call or an 'external' function call. I'm…

hyperhello on HNVery interesting. Maybe this would benefit from concrete examples, of things that are difficult or impossible in other languages, but well supported in Wyzer? I see there's a few…
andai on HNnice Rust-inspired syntax, although if the main selling point is choreography here, that isn't featured enough on web page or README. Needs more examples/explanation of how that…

Explain how choreographic programming works
From 2 comments
For anyone looking for an easily digestible primer on choreographies: https://decomposition.al/zines/communicating-chorrectly-zine.pdf Too bad the github readme doesn't explain…

Questions
How are distributed deadlocks prevented
From 1 comment
One thing I don’t understand is how you can guarantee the lack of a distributed deadlock. I’m sure it’s covered in the underlying research, but just conceptually it’s hard to…

How does Perceus handle shared data and performance
From 1 comment
> Memory (Section 5): You write functional code that does not change data. Behind the scenes, if a piece of data has only one owner, the compiler changes it directly in memory.…

Chapel

No mention of the much more mature Chapel, with industry support, given the domain?
