Right, I see what you mean!
For "default to SInt if there is currently no type set", I guess you mean doing
something like this?
```
case 'i':
if (Kind == Invalid)
Kind = SInt;
ElementBitwidth = 32;
break;
```
While it's not that different from initialising `Kind` as `SInt`, it would
allow for adding checks that something like `QUi` is not a valid typespec,
something that currently goes undiagnosed.
