Why Rocq is better than Lean for program verification
TL;DR
Rocq is preferred over Lean for program verification due to its direct support for executable coinductive predicates, which Lean lacks. This makes Rocq a better fit for specific verification tasks.
✦ Why It Matters
Consider using Rocq for your program verification projects to leverage its executable coinductive predicates.
Key Takeaways
- Use Rocq for direct support of coinductive types.
- Leverage Rocq's executable cofixpoints for program extraction.
- Avoid complex workarounds required in Lean for coinduction.
- Consider Rocq for verifying complex data structures.
How It Works
Rocq allows users to define coinductive types directly, enabling straightforward extraction of executable programs. This contrasts with Lean's QPFTypes, which requires additional layers of abstraction and does not provide native support for coinductive types.
