Modify `find_expr` from `Span` to better account for closures Start pointing to where bindings were declared when they are captured in closures: ``` error[E0597]: `x` does not live long enough --> $DIR/suggest-return-closure.rs:23:9 \| LL \| let x = String::new(); \| - binding `x` declared here ... LL \| \|c\| { \| --- value captured here LL \| x.push(c); \| ^ borrowed value does not live long enough ...
