If you had just said "DSL" instead of "anonymous protocols and dataclasses" you would have gotten straight to the point and we would have been talking about whether extended subscription would be useful for DSLs (I can see various use cases), rather than arguing over whether Struct can be spelled with () instead of [] (a total waste of time). In fact, I don't know why you think "DSL" is a naughty term.
