By the way, smart_resolve_report_errors is tooo long and seems hard to maintain 😂
Should we refactor this part? @estebank

We should, but better to do it as part of its own PR.

This can now be written as follows

Suggested change

let has_eq = matches!(sm.span_to_snippet(eq_span), Ok(ref snippet) if snippet == "=");

if has_eq {

if let Ok(ref snippet) = sm.span_to_snippet(eq_span) && snippet == "=" {

Is this check to protect against macros or something else?

Ah, yes. Saw the dbg!(binding) case in the test. Hacky, but makes sense!

emm, I will add a comment for this.

-                break;
-            }
-        }
+        let closing_span = sm.span_look_ahead(span, Some("}"), Some(50));


Since the next_point bug is fixed, this is changed from 100 to 50 😂
