Java Modules are a feature of Java itself, available since Java 9, that allows for better encapsulation.

In Gradle, each _source set_ containing Java sources can be turned into a module by adding a `module-info.java` file.
Typically, in a project with Java Modules like this one, the _main_ source set of a subproject represents a module.

```

  // Create dummy _Arg nodes. Link these to `node` and also via a control
  // dependency edge to the _SOURCE node.

    Node* node;
    string arg_name = absl::StrCat("_arg", i);
