When a block contains a [final operand], the block has the type and value of that final operand.

```rust
let x: u8 = { 0u8 }; // `0u8` is the final operand.
let x = { 0u8 }; // `0u8` is the final operand.
assert_eq!(x, 0);
let x: u8 = { (); 0u8 }; // As above.
let x = { (); 0u8 }; // As above.
assert_eq!(x, 0);
```

r[expr.block.value-no-trailing-expr]
When a block does not contain a [final operand] and the block does not diverge, the block has [unit type] and [unit value].

```rust
let x: () = {}; // Has no final operand.
let x = {}; // Has no final operand.
assert_eq!(x, ());
let x: () = { 0u8; }; // As above.
let x = { 0u8; }; // As above.
assert_eq!(x, ());
