Source Generators: Why additive only?

[flipchart]

I was really hoping for something along the lines of Rust's macro system so that I could remove some runtime updates I do to Expressions (via visitors) and replace it with compile time code. Being able to alter the code at the statement level would make C# sooo much more expressive. It could mean a lot of proposed features could be implemented as generators - like record classes.

supporting code rewrite needs more work on area like c# language, visual studio..

you can get more info on dotnet/csharplang#107
