Module visit 

AST visitor and walker traits.

This module provides the Visitor trait for traversing AST nodes, and the walk module with default traversal implementations.

Design

• The Visitor trait has a visit_* method for each AST node type.
• Each visit_* method has a default implementation that calls the corresponding walk_* function, which recurses into children.
• Override individual visit_* methods to intercept specific node types without reimplementing the full traversal.

Extension

As the AST grows (PARSE-004 through PARSE-011), new visit_* / walk_* pairs will be added. The existing visit_source_file entry point dispatches to all child nodes.

Modules

walk

Default traversal implementations.
