Joining the list

HI Lee,

Your email isn't meant for me, but I'm doing some holiday
experimentation too, and can help with the last part. In Intellij, go
to Project Structure, set the Project SDK to your Java 16 build, and
Project Language Level to 'SDK default (X - Experimental Features)'.
Make sure your maven compiler configuration is updated as well:

```
<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.8.1</version>
      <configuration>
        <release>16</release>
        <compilerArgs>
          <arg>--enable-preview</arg>
          <arg>--add-modules</arg>
          <arg>jdk.incubator.vector</arg>
        </compilerArgs>
      </configuration>
    </plugin>
  </plugins>
</build>
```

Everything will then 'just work.' I don't use Eclipse, but I imagine
it's more difficult since they have their own incremental compiler.
