Can a production system expose small, editable behavioural views?
- Program slicing can recover relevant behaviour; amorphous slicing can simplify its representation.
- Bidirectional transformations and lenses study how to propagate changes between different representations.
- The hard part is reintegration: an edit to one slide may affect shared classification or exclusion behaviour elsewhere.
- A useful compiler must retain provenance, reconcile overlapping views and preserve unaffected guarantees.
