C# - Missing keywords

[makolyte]

I noticed some missing keywords from the latest versions of C#:

• record

Example:
public record Movie(string Title);

• with

Example:
var m = a with { Name = "Test"}

These were new keywords added in .NET 5 / C# 9. I'm kinda guessing there might be other missing keywords from the latest versions. I haven't noticed any, just these two.
