Procedural-like Syntax Layer for Beginners in C#

[EdvaldoDantas]

As a suggestion to make C# more beginner-friendly, especially for those coming from procedural languages like C or Python, I propose the introduction of a "procedural-like" syntax layer in C#.

The idea is to allow developers to write simple functions in separate files without needing to define classes or access modifiers. For example:

int Sum(int x, int y) { return x + y; }

Behind the scenes, the compiler would transform this into:

public static class SumFile {
public static int Sum(int x, int y) { return x + y; }
}

And to call it:

SumFile.Sum(2, 3);

This would provide a more approachable experience for newcomers by reducing initial syntax overhead, while still compiling into proper, structured C# code. It builds upon the existing top-level statements feature and expands it for better modularity.

I believe this feature could attract more students and beginners to the C# ecosystem.

It's very disliked to make the code sensible to make the code sensitive to file system. See dotnet/csharplang#2908 dotnet/csharplang#4722
