Procedural macro to extend the lifetimes of temporary variables.
See working examples for more examples.
```rust use hoisttemporaries::hoisttemporaries;
fn main() { let mut snack = "Cheese"; if true { // Without hoisttemporaries, this would error because the format!() returns a temporary which would otherwise be dropped because it has no owner. snack = &format!("{}burger", snack); } asserteq!(snack, "Cheeseburger"); } ```
