Some more resources from that post:

> See examples (https://github.com/Panzerschrek/U-00DC-Sprache/tree/master/s...) to get a general idea what Ü is and how it looks like and feels. Read the documentation (https://panzerschrek.github.io/U-00DC-Sprache-site/docs/en/c...) for more details. If you have some questions about the specific mechanism providing safety, read the corresponding chapter (https://panzerschrek.github.io/U-00DC-Sprache-site/docs/en/r...). If some topic isn't clear for you after reading the documentation, contact me and I can answer your questions.
