## Events
Events are finally in! To do events properly, we are abstracting over the event source with synthetic events. This forces 3rd party renderers to create the appropriate cross-platform event
## Optional Props on Components
A major goal here is ergonomics. Any field that is Option<T> should default to none.
```rust
rsx! {
Example { /* args go here */ a: 10, b: 20 }
}
```
```rust
#[derive(Properties)]
struct Props {
}
static Component: FC<Props> = |ctx, props| {
}
```

```rust
