dynamicMemberLookup bug?

[tera]

@BastianKusserow

Honestly I'd expect that the compiler prioritises the get/set of Foo itself, why I guess the subscript is not called.

Don't you think it's strange that compiler accept it as a requirement and then simply ignores it?

@BastianKusserow

Is there a particular reason why you'd like to have dynamicMemberLookup with members being the members of the type where the attribute is applied to?

I'm exploring various observation machinery implementations. See the relevant thread.
