Explores advanced optional parameters & named arguments as a Java compiler plugin. Complete IDE integration available with IntelliJ.

Key features

- Optional parameters -- Define default values directly in methods, constructors, and records

- Named arguments -- Call methods using parameter names for clarity and flexibility

- Flexible defaults -- Use expressions, reference earlier parameters, and access local methods and fields

- Customizable behavior -- Override default values in subclasses or other contexts

- Safe API evolution -- Add parameters or change defaults without breaking binary or source compatibility

- Eliminates overloads and builders -- Collapse boilerplate into a single, expressive method or constructor

- IDE-friendly -- Fully supported in IntelliJ IDEA and Android Studio
