Language-suggestions VS Roslyn

Admittedly, knowledge is a little scattered, we juggle it between the specs/ideas repo and our Discord server (our main way of communicating currently). There are a few examples in the Ideas/Specs repo. A contributor has also proposed starting to work on an interactive tutorial, since we can run the compiler and editor in web, we might do that to collect all stable capabilities of the language soon.

Absolutely. And one guy's already working on that, I hope it will one day become a reality. [Link](https://github.com/LanguageDev/Fresh-Language-suggestions)

I've written 2 issues closely related to my opinions on C#. One is a general collection (this), one is a journey through the version history (here).

The C# compiler has an MIT license and is available on GitHub, which is about as FOSS as it gets.

My understanding is that the .NET team is working toward this with Interceptors: https://github.com/dotnet/roslyn/blob/main/docs/features/int...

.NET is a little smarter about switch code generation these days: https://github.com/dotnet/roslyn/pull/66081

Recently, while creating some experimental C# source code generators (xafero/csharp-generators), I was just concatenating strings together. Like you do, you know, if things have to go very quickly. If you have a simple use case, use a formatted multi-line string or some template library like scriban. But I searched for a way to generate more and more complicated logic easily - like for example, adding raw SQL handler methods to my pre-generated DBSet-like classes for my ADO.NET experiment. You could now say: Use Roslyn and that's really fine if you look everything up in a website like SharpLab, which shows immediately the syntax tree of our C# code.

At runtime, the Case C# expressions are embedded into a function and dynamically compiled into an assembly using the Roslyn C# compiler. Then the function that contains the expression is called (e.g. CaseAvailableFunction.Availablle()). At runtime, the function provides various methods to access stored case values as well as the current input data.
