First of all, I want to express my gratitude to all contributors working on the integration of changes and tests.

In today's development landscape, especially when working with AI-assisted coding, providing the best possible code context is crucial. The integration of outgoing calls functionality can significantly improve this aspect.

The main benefit of implementing outgoing calls would be context extension. This feature would:

- Allow developers to see function call relationships
- Help identify potential impacts when modifying functions
- Provide better context for AI-assisted development
- Improve code maintenance and refactoring workflows

When modifying a function, developers would have immediate visibility of all called functions that might need corresponding updates, reducing the risk of introducing bugs.
