Semantic identifier naming patterns

Use consistent naming patterns that reflect the semantic role of identifiers:

1. Constants should use UPPER_SNAKE_CASE:

   const MAX_RETRY_COUNT = 3;
   const API_BASE_URL = "https://api.example.com";
   

2. Type names should use TitleCase:

   struct UserProfile { }
   class DatabaseConnection { }
   

3. Functions/methods should use camelCase:

   fn calculateTotal() { }
   fn validateUserInput() { }
   

4. Member variables should use a consistent prefix (e.g., m_) to clearly identify class/struct members:

   struct Widget {
    m_width: i32,
    m_height: i32
   }
   

This pattern makes code more readable by allowing quick visual identification of an identifier’s role. It also helps catch semantic errors where identifiers might be used incorrectly (e.g., using a type name where a function was intended).
