Proposal: Support for static readonly fields as case patterns in switch statements/expressions

[pikoscielniak]

I would like to propose, or inquire about the official support for, using static readonly fields of a class or record directly as patterns in switch statements and switch expressions.

I would like to propose that this construct be considered valid language syntax and compilable, but under the current rules, it is not allowed:

var value = SomeValueObject.ValueOne;

var result = value switch
{
    SomeValueObject.ValueOne => "This is one",
    SomeValueObject.ValueTwo => "This is two",
    SomeValueObject.ValueThree => "This is three",
    _ => "I don't know what this is"
};

Console.WriteLine(result);


public record SomeValueObject(string Value)
{
    public static readonly SomeValueObject ValueOne = new("one");
    public static readonly SomeValueObject ValueTwo = new("two");
    public static readonly SomeValueObject ValueThree = new("three");
}

I was wondering if there are any plans to support something like this in the future?

Static readonly is not anything special at the view of high level language. See #4321 and #6947.
