We apologize for taking so long to take a look at this. Could you elaborate on what exact problem you encounter in Scala?

• Is this a functionality issue, i.e. is something broken in a Scala project and you need this change to fix it? If so, please provide some sort of example to reproduce the issue.
• Or is this merely a convenience issue (e.g. "the class is written without a $ in Scala but the ArchUnit report shows a $ symbol")? In that case, we would stick to what it says in the class file.
