# Challenges and Optimization:
# Path Resolution: Converting imports to file paths is specific to your project's structure and may require custom logic.
# Performance: Recursively parsing and gathering code can be resource-intensive. Consider optimizations like caching parsed files.
# Circular Dependencies: Implement checks to avoid infinite recursion in case of circular dependencies.
