6. Related Work: Torch
• Not designed for Pull Request.
• Made for Monticello.
• We take inspiration on Torch:
• Contextual diff.
• Embedded chart for metrics.

numpy/numpy pull
request number 8939, in
Python
pharo-vcs/iceberg pull request number 325

8. Limitations
• Missing the comments.
• History noise.
• Pull request with many commits.
• Unrelated changes in single pull request.
• Torch does also have this problem.

9. Future Work
• Incorporate the Pull Request Comments.
• Validation and Experimentation.
• We will experiment with Pharo and Python
practitioners.
• Arbitrary commits.
