error[E0382]: use of moved value: `b`
--> $DIR/borrowck-consume-upcast-box.rs:10:13

LL | fn foo(b: Box<dyn Foo + Send>) {

LL | consume(b);
| - value moved here
LL | consume(b);
| ^ value used here after move

note: consider changing this parameter type in function `consume` to borrow instead if owning the value isn't necessary
