Yes, I just ran a test after cloning
[scalariform](https://github.com/scala-ide/scalariform) which
[scalastyle](https://github.com/scalastyle/scalastyle) uses as below:
```
ScalaLexer.rawTokenise("@Override")
```
It seems this becomes
different tokens.
(BTW, maybe we should avoid to write `@Override` as it is.. I started to
feel guilty for cc him/her here and there....)
