error[E0597]: `a` does not live long enough
--> $DIR/borrowing.rs:18:29

| || borrowed value does not live long enough

| `a` dropped here while still borrowed
|
= note: The temporary is part of an expression at the end of a block. Consider forcing this temporary to be dropped sooner, before the block's local variables are dropped. For example, you could save the expression's value in a new local variable `x` and then make `x` be the expression at the end of the block.
