@Kha We will probably have to refine the heuristic for hiding the inaccessible names, but the first version is already useful. Here is the error message for a `_` before this commit ``` error: don't know how to synthesize placeholder context: x✝⁴ : List Nat x✝³ : Nat x✝² : x✝⁴ ≠ [] a b x✝¹ : Nat x✝ : [a, b] ≠ [] ⊢ Nat ``` After ``` error: don't know how to synthesize placeholder a b : Nat : [a, b] ≠ [] ⊢ Nat ```
