// Test that we give a custom error (E0373) for the case where a
// closure is escaping current frame, and offer a suggested code edit.
// I refrained from including the precise message here, but the
// original text as of the time of this writing is:
//
//    closure may outlive the current function, but it borrows `books`,
//    which is owned by the current function
