You can use the .sizeof property on the type.
```
import core.simd;
void main() {
ubyte16 a;
ushort8 b;
pragma(msg, a.sizeof);
pragma(msg, b.sizeof);
pragma(msg, a[0].sizeof);
pragma(msg, b[0].sizeof);
pragma(msg, typeof(a[0]));
pragma(msg, typeof(b[0]));
}
```

Brilliant. I am sooo stupid, I forgot you can access SIMD
variables like normal arrays. Thank you for waking me up again :-)
