- Introduced new stages in the course definition for implementing the `super` keyword, allowing methods to call overridden methods from their superclass. - Added validation for incorrect usages of the `super` keyword, ensuring appropriate error messages and exit codes are provided. - Updated marketing materials to reflect the new focus on `super` keyword functionality and validation in the Lox interpreter.
- Updated the course definition to include a new stage focused on validating the usage of the `super` keyword, ensuring it is only used in appropriate contexts. - Added detailed descriptions and examples for invalid usages of `super`, along with expected error messages and exit codes. - Revised existing content for clarity and consistency in error reporting related to class hierarchies and the `super` keyword.
- Revised the course definition to enhance clarity in the descriptions of exit codes for valid and invalid class hierarchies. - Removed redundant lines while ensuring the expected behavior for compile-time and runtime errors is clearly stated.

7121-7131: Stage "Overriding Methods" & Trailing Spaces
The "Overriding Methods" stage is clearly described. However, YAMLlint has flagged trailing spaces on line 7121. Please remove these extra spaces to maintain consistent formatting. For example, you might change:- name: "Overriding Methods"␣␣ + name: "Overriding Methods"Once that is fixed, the stage description appears to be in line with our guidelines.

113-120: New "Inheritance" Extension Added
The new extension for inheritance is introduced consistently with the other extensions. The section clearly describes its purpose (handling class inheritance, method overriding, and the super keyword) and properly references the relevant chapter of the book.
6912-6948: Stage "Class Hierarchy" Added
The "Class Hierarchy" stage lays out clear instructions for enabling inheritance using the<operator. The description includes a proper book reference and suggests that tests will verify instance printing (e.g. "A instance", "B instance", etc.). Please double-check that the test cases cover both simple and nested inheritance scenarios.
7016-7054: Stage "Inheriting Methods" Added
This stage introduces method inheritance. The description clearly explains that subclasses can inherit methods from their superclass, and the associated book section is correctly referenced. Ensure that the tests validate that inherited methods are correctly available across different inheritance levels.
7259-7273: Stage "Invalid Class Hierarchies" Added
This stage adds validation for improper class inheritance (e.g. a class inheriting from itself or non-class entities). The description is comprehensive and references the correct book section. Please verify that error messages and exit codes are correctly implemented in the interpreter.
7337-7346: Stage "ThesuperKeyword" Added
The new stage to support thesuperkeyword is well-described and correctly references the documentation for calling superclass methods. Ensure that test cases verify thatsupercorrectly calls methods from the parent class and that it is bound to the right instance context.
7427-7505: Stage "Invalid Usages of thesuperKeyword" Added
This stage focuses on validating thatsuperis used only in appropriate contexts. The description is detailed and clearly specifies common misuse scenarios (such as usingsuperoutside a subclass or not followed by a dot). Please make sure the interpreter provides clear error messages (with exit code 65) when such invalid usages are encountered.

7121-7126: Stage "ka5" (Overriding Methods): Trailing Whitespace Issue
The “Overriding Methods” stage is well described and explains that subclasses can supply their own implementations of inherited methods. However, YAMLlint has flagged trailing whitespace on line 7121. Please remove these extraneous spaces to keep the file formatting consistent.- (trailing spaces at end of line 7121) + (line 7121 cleaned of trailing spaces)🧰 Tools

113-120: New Inheritance Extension Added
The new extension “inheritance” is introduced with a clear name and description. The markdown succinctly explains that this extension covers chapter 13 of the book and will add support for class inheritance, method overriding, and the super keyword. The formatting and naming follow the conventions used by the other extensions.
6912-6918: Stage "mf6" (Class Hierarchy) Check
Please verify that the new stage (slug: "mf6" – Class Hierarchy) correctly explains how users can define class hierarchies using the<operator. The description should include sufficient detail with examples and tests to cover the intended behavior as described in chapter 13. Let me know if you need help generating example test cases.
7017-7024: Stage "ky1" (Inheriting Methods) Overview
The “Inheriting Methods” stage appears to provide a clear explanation of subclass method inheritance. Confirm that the test cases referenced will cover the common inheritance scenarios so that methods defined in a superclass are inherited and callable on subclass instances.
7259-7267: Stage "ab0" (Invalid Class Hierarchies) Validation
This stage introduces checks to detect invalid class hierarchies (for example, a class inheriting from itself). The description is thorough and clearly states the objective. Please confirm that the test cases cover the edge cases and that the error messages (and exit codes) are consistent with the rest of the interpreter.
7337-7345: Stage "qi0" (Thesuperkeyword) Functionality
The “Thesuperkeyword” stage provides a good description of how the interpreter will support calling overridden methods from a superclass. Double‐check that the corresponding tests mirror the examples in the Crafting Interpreters book and that error handling is correctly implemented when the keyword is misused.
7427-7505: Stage "ib9" (Invalid Usages of thesuperKeyword) Error Handling
This stage adds validation to ensure that thesuperkeyword is used only in the proper contexts. The description is clear about detecting and reporting errors whensuperis misused (for example, when it appears in a class with no superclass or is used outside a method). Please ensure that the implementation raises a compile‐time error (exit code 65) and that the tests cover all invalid usage cases as described.
- Revised stage names in the course definition to improve clarity and consistency, specifically for stages related to class inheritance and the `super` keyword. - Adjusted names to remove backticks and ensure proper formatting for better readability.
