x: i32 | 3, // signed integers will be signed extended on use
y: u16 | 2 + 3, // general expressions
z: My_Enum | foo.SOME_CONSTANT, // ability to define the bit-width elsewhere
w: bool | foo.SOME_CONSTANT > 10 ? 2 : 1,
}
```
```
Handle :: bit_field u32 {
slot: u32 | 16,
generation: u32 | 15,
in_use: bool | 1,
}
```
