Core Syntax and Semantic Rules

• Identifier conventions and standards
• Commenting syntax, including block-level annotations
• Management of global state and enforcement of strict variable scoping
• Definition and scope of local variables
• Execution of standalone applications and handling of program arguments

Iterators and Coroutines

• Utilization of the generic for loop
• Distinction between stateless and stateful iterators
• Comparative analysis of iterators versus coroutines

Metatables and Metamethods

• Case study: Implementing set logic
• Application of the __tostring metamethod
• Definition of arithmetic metamethods
• Implementation of __index and __newindex metamethods
• Application of the __len metamethod

Modules and Package Management
