Currently we send each instruction as a full JSON blob – this unnecessarily increases the amount of data we need to transfer. We might want to go for a more Liveview-esque system (they send the data in two parts "static" and "dynamic", updating as needed), or design a custom format that is more efficient.

Asides from this, we might want to batch multiple diffs together, sending them in a single WebSocket frame (because each new frame incurs some extra overhead).

It would be great to have a system for testing applications.

To start with we should be able to send requests and check their responses.

It's also worth thinking about adding a system for testing more complex applications (i.e. that things happen correctly when there's communication between request handlers, rather than each response being only a function of the request).

Running either the chat or list examples has this error:

Error: unknown import: `lunatic::process::inherit_spawn` has not been defined

We should ideally have a form parser, for parsing HTTP forms.

Initially just plain forms should work, but multipart forms would also be nice.

With lunatic-runtime version 0.10: cargo run --bin list yields:

Error: unknown import: `lunatic::process::inherit_spawn` has not been defined
