I think:
```
if (isKnownToBeTypeSpecifier(GetLookAheadToken(1)))
```
will need to be factored away, then. When I looked into this, the issue is that
the token we get is not actually annotated because nothing calls a
`TryAnnotate*()` function to turn it into an annotation token. IIRC, those
functions all work off `Tok`, not a given `Token`, and they work by modifying
the token stream itself (so may not work well as a lookahead function).
