-Symbols representing class names are resolved to the Class instance. Inner or nested classes are separated from their outer class with a `$`. Fully-qualified class names are always valid. If a class is `import`ed in the namespace, it may be used without qualification. All classes in java.lang are automatically imported to every namespace.
