@Kha this commit fix another example of weird error message I have experienced in the last few days. The macro ```lean syntax "case!" ident ":" term "with" term "," term : term macro_rules | `(case! $h : $cond with $t, $e) => `((fun $h => cond $h $t $e) $cond) ``` is accepted, but as in `fun` binders, we get a weird error when trying to elaborate an instance of the macro. Example: ```lean check case! h : 0 == 0 with h, not h ``` |
