Test "tutorial/119_reflOccInIndex"

Expected: ✋ reject · Size: 3.9 KB · Lines: 66 · lean4export: 3.1.0 · Lean: 4.29.1 · 📄 Declaration · 🔗 Source

Rejection: recursive occurrence in index position, behind a further arrow.

We build an indexed inductive I : Type → Type with a constructor argument Nat → I (I α), so the recursive occurrence appears as an index argument.
