error[E0716]: temporary value dropped while borrowed
--> $DIR/borrowck-let-suggestion.rs:2:17

LL | let mut x = vec![1].iter();

| creates a temporary value which is freed while still in use

LL | x.use_mut();

= note: this error originates in the macro `vec` (in Nightly builds, run with -Z macro-backtrace for more info)
help: consider consuming the `Vec<i32>` when turning it into an `Iterator`

LL | let mut x = vec![1].into_iter();

help: consider using a `let` binding to create a longer lived value

LL ~ let binding = vec![1];
