So much Claude text. I'm sure this is great (I did a bunch of stuff with/to aardappel's lobster, years ago, and it was pretty tidy, and quite easy to work with), but: Claude's writing makes my brain melt.
Yeah it's very clear at the bottom that it's created by AI. I think this is an interesting case where someone with some great ideas they never got to can actually implement them. I personally hate the Claude style, but just looking at the samples was enough to get a feel for the language.

So it looks like it restricts the memory management to 100% scope based. I expect that makes a lot of designs for programs not translate to it as well as they fit in Rust or Java (for example). There are a bunch more constraining design choices they list further down:
> - Nothing ever moves
> - ... A string, an array of strings, a record with variable-size fields and an array of those records are each one contiguous block with no pointer in it
I'll have to look a bit deeper to decide if it's feasible to write many things in this language.
Say you wanted to make a Node.js framework with callbacks that react to an event. The callback might be a closure that captured some of its surrounding variables. At that point, any of the captured variables are not trivially stack-allocated.
You might be able to do something similar to what Rust does with moving though.
You could predefine your event handlers within your context, then call 'enter framework' and pass your event handlers as arguments. this is continuation passing style
116% would be 2x which will break the laws of physics. 16% is possible if you're not allocating heap memory, which I believe is the main selling point here.
I am researching a similar idea but which allowed moves if the compiler was able to fix the resulting structure, but mine will probably stay a small side project for a long time.
If I am reading it correctly, the compiler creates N bump allocators per function (or possibly globally) - where N is (I'm guessing at this point) determined by liveness or similar.
How big is the stack? Too often large data will blow the top and destroy adjacent stacks in multi-thread environments. Are memory barrier fences used to check against overflow?
It's a no from me. I'm sorry.

I was thinking about making a language with same thoughts: Safer than C++ and faster than rust (and a 3rd thing: optimized for AI)
and you actually did it for me. Hooray!
Just the AI language optimization thing is missing..
Isn't this kind of the point of Java's Project Valhalla or am I just confused???
(Feels like it should probably say "1.16x as fast" or "1.16x the throughput" - or something like that.)
