Object-oriented programming support

[lcnvdl]

This ticket aims to introduce comprehensive support for object-oriented programming (OOP) in HtmlGo. The goal is to enhance the language with essential OOP concepts, such as classes, objects, inheritance, and encapsulation, enabling developers to write more modular and reusable code.

Key Objectives:

• Implement a class-based system: Define a syntax for creating classes, including class declarations, constructors, and methods.
• Enable object instantiation: Allow developers to create instances of classes using constructors.
• Support inheritance: Introduce the ability to create derived classes that inherit properties and methods from base classes.
• Encapsulate data: Provide mechanisms to control access to class members, allowing for data encapsulation and abstraction.
• Implement method overriding: Allow derived classes to override methods inherited from base classes to provide customized behavior.
• Support polymorphism: Enable the use of polymorphic behavior by allowing methods to be overridden and called dynamically based on the actual object type.
• Provide access modifiers: Introduce access modifiers like public, private, and protected to control the visibility and accessibility of class members.

By implementing object-oriented programming support in HtmlGo, we aim to empower developers to build more robust and scalable applications, promoting code reusability, maintainability, and overall code organization. This ticket will involve significant changes to the language's core functionality and syntax, and it will require careful design and implementation considerations.

Contributions and suggestions are welcome as we work together to bring object-oriented programming capabilities to HtmlGo and unlock its potential for building sophisticated applications.

Please feel free to provide feedback, ask questions, and contribute to this ticket. Let's make HtmlGo an even more powerful and versatile language!

• Class Definitions: Implement the syntax and semantics to define classes in HTML Go.
• Attributes: Allow defining attributes (fields) within classes to store data.
• Methods: Add support for declaring methods (functions) inside classes to define behavior.
• Inheritance: Implement the ability for classes to inherit properties and methods from parent classes.
• Polymorphism: Enable polymorphism, allowing objects of different classes to be treated as objects of a common superclass.
  Additionally, consider the following tasks to fully support object-oriented programming:
• Encapsulation: Ensure that class members are properly encapsulated to control access.
• Abstraction: Support abstract classes or methods to define common interfaces.
• Interfaces: Add support for interfaces to define contracts for classes to implement.
• Constructors: Implement constructors to initialize objects when they are created.
• Destructors: Allow for proper cleanup of objects when they are no longer needed.
• Access Modifiers: Introduce access modifiers like public, private, and protected to control member visibility.
