error[E0106]: missing lifetime specifier
  --> $DIR/bad-lifetimes.rs:3:39

LL | fn no_elided_lt() -> impl Sized + use<'_> {}
   |                                       ^^ expected named lifetime parameter
   |
   = help: this function's return type contains a borrowed value, but there is no value for it to be borrowed from
help: consider using the `'static` lifetime, but this is uncommon unless you're returning a borrowed value from a `const` or a `static`, or if you will only have owned values
