C# 14 Extension Members - Implement Interface

[ghost]

Hi, can the new C# 14 feature, Extension Members, be used to implement interfaces?

https://github.com/dotnet/csharplang/blob/main/proposals/extensions.md

If not, is any new feature planned to allow a more stand-alone approach to associating interface-implementation functions to data types/structs? C# extension methods are excellent, however, I propose that this approach become normalized (functional programming, pattern matching).

(In general, I propose the idea of evolving away from the hidden this pointer altogether, but I do understand, one step at a time.)

Thank You

No.

We are looking into such a thing under the name "roles"

OK. From both answers, I think that I have a sense of the strategy. Thanks kindly.

@CyrusNajmabadi is there a document I can read about this?
