For example, how do you negate a ubyte?

Mathematically this is only defined for 0 over the range of
ubyte.

Obviously, you can't do this:

```
        ubyte a;
        a -=;
```

But writing it as `a = -a;` runs into the same error, for the same reason.

Instead, you have to work around it with this baroque periphrasis:

```
        ubyte a;
        a = cast(ubyte) -a;
```

Does it make sense?

How about:

```
   a *= -1;
```

?
