Thank you very much for the additions.

If you could please replace the tabulators with space characters, I would be happy to merge the pull request.

However, note that some of the error messages you added are deprecated and obsolete, i.e. they will never actually appear.

Glad to hear you accept my pull request. Editing on Github seems to automatically have turned spaces around '=>' into tabs. I changed them offline.

As for some messages being obsolete, I did not dive into the logic of the error types but started from ErrorCode.scala and worked with the available localisations. So I hope my translations do reflect the proper semantics.

Thanks again for this incredibly valuable piece of software! I intend to combine it with Moodle to automate testing of beginner-level programming courses. For years, I have used TigerJython for this purpose (via ch.aplu.turtle) but the installation was literally drowned by a flash-flood. In the course of re-writing the code I am moving away from Java to Python3 but still wanted to maintain the helpful error messages from TigerJython.
