The module loading logic has been refactored to enhance readability and
maintainability. Key changes include:
* **Path Handling**: Simplified path construction using `join` for
better clarity and consistency.
* **Error Reporting**: Improved error messages during parsing by
utilizing `parser.diagnostics.format_errors()`.
* **Module Loading Logic**:
* The `loaded_modules` set now uses `insert()` to both add new
modules and efficiently check for duplicates, returning `false`
if the module was already loaded.
* The recursive call to `collect_dependencies` is now placed
before processing the current file's AST, ensuring a topological
order of dependency loading.
* **Helper Function Scope**: `extract_use_directives` is now a static
method as it doesn't depend on the `ModuleLoader` instance.
