Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

What the imperative shell of an Functional Core/Imperative Shell language looks like
I like it. Modern languages that distinguish between pure and impure programs like Flix, Koka, and Effekt do so on the type level instead of syntactically. This has three advantages:
-
Algebraic Effects: Another mistake carried through to perfection?
The problem with checked exceptions been identified and solved. The same problem and solution applies to effect handlers. Effekt is a language with lexical effect handlers which doesn't have this problem. Consider the following program in Effekt:
-
Is continuation passing style conversion still used as an intermediate language?
Yes, for you this is the right decision. But for us going to CPS makes everything significantly easier and in cases where you do use control effects significantly faster. For our language Effekt we are exploring different tradeoffs in different backends.
-
The Registers of Rust - Without boats, dreams dry up
This pattern they observe is nicely captured by effect handlers. These examples are written in Effekt.
-
An approach to manual memory management and side effect handling system, feedback, ideas and thoughts requested
This is beyond my level of expertise. But effect tracking? There are some cool languages out there that do that consistently! Search for "algebraic effects". My favorite is Koka. Effekt also seems to be a popular choice.

Is there a garbage collected, statically typed language, that has null safety, and doesn't use exceptions?
Examples are languages like Koka, Effekt, Links, or Unison. These languages come with a type-and-effect system: a function's type not only tell you which values the function accepts and which values it returns, but also which effects it has. This is relevant to your question, because throwing an exception is one such effect.
-
The Val Object Model: Template for a possible future Swift object model
It seems that with Effekt we are pursuing the same goal, but coming from the opposite direction, perhaps one day we will meet in the middle :). We start from a purely functional language and carefully add effects like mutation.
- Is there a pure-functional ML?

Cpp2 and cppfront – An experimental 'C++ syntax 2' and its first compiler
The evolution of C++ has been a multi-decade history of dealing with difficult reality.
I have great hope that Herb can create with his cppfront project “The Very Best of C++” to carry that tremendous legacy forward.
If I was to throw my hat into a “C++ successor”, it would be https://www.hylo-lang.org/ with its “all the safeties” and “tell you when you’re doing it sub-optimal” approach.

Borrow Checking Hylo [video]
Paper: https://2023.splashcon.org/details/iwaco-2023-papers/5/Borro...
> Hylo is a language for high-level systems programming that promises safety without loss of efficiency. It is based on mutable value semantics, a discipline that emphasizes the independence of values to support local reasoning. The result—in contrast with approaches based on sophisticated aliasing restrictions—is an efficient, expressive language with a simple type system and no need for lifetime annotations.
> Safety guarantees in Hylo programs are verified by an abstract interpreter processing an intermediate representation, Hylo IR, that models lifetime properties with ghost instructions. Further, lifetime constraints are used to eliminate unnecessary memory allocations predictably.

Why do lifetimes need to be leaky?
A model without lifetimes is also being explored in other languages, e.g. in Hylo. It sacrifices expressiveness, but on the other hand you don't have to deal with explicit lifetimes!
-
D Programming Language
Why go through all the trouble when you can do this: https://www.hylo-lang.org/ and not spend a second thinking of lifetimes? No, copies will not be issued unless necessary.
Or why not keep exploring this idea as well? More research-oriented than the first one right now, though, so take it with a grain of salt: https://vale.dev/

I've heard that "Rust's borrow checker is necessary to ensure memory safety without a GC" usually also implying it's the only way, but I've done the same without the borrow checker. Am I just clueless/confused?
