// This is a test for the new temporary lifetime behaviour as implemented for RFC 3606.
// In essence, with #3606 we can write the following variable initialisation without
// a borrow checking error because the temporary lifetime is automatically extended.
// ```rust
// let x = if condition() {
// &something()
// } else {
// &something_else()
// };
// ```
// More details can be found in https://github.com/rust-lang/rfcs/pull/3606
