Isn't this equivalent to:
```
switch (size)
{
case 1:
case 2:
case 4:
case 8:
break;
default:
return false;
}
```
? That definitely seems much clearer.
I'm also pretty sure that on x86 you can't add a 64-bit watch, So you'd have to
do something different depending on the target bitness if you want this to be
correct for x86.
