How is this different than C#? What new concepts does this bring that C# doesn't?
20 years ago there was some momentum behind Visual Basic .Net; but the language was so similar to C# that it just wasn't worth using. There was a joke that .Net was a "skinnable language."
BTW, there's a whole nitpicky/semantic argument that C# isn't null safe because of the null forgiving operator. That will probably come into play with G# if the null forgiving operator can be used from C# to pass null into G# code that doesn't expect it.
I wish README is clear whether they are using AI or not, and if so what the guidelines are. Not that anything wrong with using it, but given anyone with $$$ for tokens can do it, its nice to know what their process is etc etc. Gives me more confidence that its worth checking out.
Just trying to offer some help here, not an attack:
```
G# brings Go-, Kotlin-, and Swift-style ergonomics — packages, func, data class, nullable handling with if let, structured concurrency with scope — to the .NET runtime. Source compiles directly to managed assemblies.
```
This is a decent description - but as someone also building a language in a similar space - who isn't super familiar with the .NET runtime... My first question is... Why not C#?
I'm by no means a C# expert, but I thought most of this was supposed to be in C#. C# is not terribly un-ergonomic, and Go is simple, but not really ergonomic except for Goroutines...
`packages` and `func` being the first two selling points is alarming. Sure, people probably prefer `fn foo() -> Dog` over `Dog foo()`. No one's picking a language for that. C# has namespaces... C# has `record` and `record struct`. C# has not-ideal nil handling, but it still has it. I'm not convinced `if let` is better enough to be a selling point - a lot of people don't like that!
Your main selling point seems like `scope` and your concurrency model vs C#, but C#'s is not exactly terrible...
Rich Hickey has a joke about semi-colons in language design, and your main pitch seems to sell yourself short.
Btw, I think your GitHub page does your language a lot better justice.
"I'm already quite sure how I will die: I'll read another article on Hacker News about a new programming language where I see nothing new, and I'll read that they included {}; to make C programmers comfortable. I'll have a massive stroke."
I feel like we've done full circle. Languages are back to being (mostly) procedural. I'm not sure I like it, but it seems that this is what people prefer.
Personally, I'd rather see something like dependant types on a dotnet language. An addition, not just a simplification.

Is this an actual shift, or is this just what happens when LLMs make it possible for anyone to build a language quickly?
This one feels less like someone thought carefully about what semantics they wanted to have and more like someone without a lot of familiarity with the design space of programming languages decided to build one that had all their favorite features from the languages that they already know:

Nothing wrong with that at all, I love to see the increased interest in language design, but I wouldn't read a shift in preferences into this wave of PLs. It's a shift in who is writing PLs, not a shift in preferences.

What is it bringing from those languages? The FAQ reads like it is just altered syntax for C#, no difference in semantics or function.

I didn't see semicolons, but I saw plenty of {} braces, and I can't explain why they're needed.

"Curly braces" (a.k.a. "{}") make lexicographical scope simpler to manage for lexers and parsers. Alternate grammar increase compiler complexity, excluding trivial token replacement.
As for semicolons, they are only a linguistic requirement for supporting multiple executable statements on the same source-code line.
I like it. I consider myself picky with regards to weird syntax in new languages and this is terse and very readable. Approved!
Looks nice, congratulations.
