// build-pass (FIXME(62277): could be check-pass?)
// rust-lang/rust#32382: Borrow checker used to complain about
// `foobar_3` in the `impl` below, presumably due to some interaction
// between the use of a lifetime in the associated type and the use of
// the overloaded operator[]. This regression test ensures that we do
// not resume complaining about it in the future.
