error: future cannot be sent between threads safely
--> $DIR/issue-70935-complex-spans.rs:13:45

LL | fn foo(tx: std::sync::mpsc::Sender<i32>) -> impl Future + Send {
| ^^^^^^^^^^^^^^^^^^ future created by async block is not `Send`
|
= help: the trait `Sync` is not implemented for `Sender<i32>`
note: future is not `Send` as this value is used across an await
--> $DIR/issue-70935-complex-spans.rs:19:11

LL | baz(|| async{
| _____________-
LL | | foo(tx.clone());
LL | | }).await;
| | - ^^^^^^- the value is later dropped here
| | | |
| |_________| await occurs here, with the value maybe used later
| has type `[closure@$DIR/issue-70935-complex-spans.rs:17:13: 17:15]` which is not `Send`
error: aborting due to previous error
