No, they don't. In fact, if you search "event" in the proposal you get exactly one result, the prefix of "eventually". This is a serious shortcoming of the proposal that should be addressed.

I think the comment you're replying to is referring to the pub/sub sections of the proposal. They don't explicitly mention events, but events are a subset of the publish/subscribe pattern.

But then so are signals.
The only "benefit" signals as proposed here give you is less control over the exact dispatch pattern of the graph, for instance things like debouncing, throttling, batching, etc etc etc. Aka all the things you absolutely must have control over if you want to make something resembling a high performance application.

Signals are not a subset of events. Signals combine event subscription with value construction, which promotes a remote declarative model for updates.

Events don't give you any more control over those properties than signals, they just require more boilerplate.

Oh, come on. They do have an example of architecture, not literal example of events. It doesn’t matter what trivial implementation of Observer pattern you choose.

Except one is already built into the language? And it provides all the upsides of signals with none of the downsides? (Modulo proper use of `using` directives)
