Ein Remake von @Ijon Tichys Antwort mit `l3keys`. Um mehr über das Zeug zu lernen empfehle ich die beiden Artikel von Joseph Wright aus TUGboat:
- [https://tug.org/TUGboat/tb31-1/tb97wright-l3keys.pdf](Programming key–value in expl3)
- [https://www.tug.org/TUGboat/tb30-1/tb94wright-latex3.pdf](LaTeX3 programming: External perspectives)
---
Vielleicht kann mir noch jemand erklären warum ich keinen LaTeX3 kernel error bekomme wenn ich `file=...` weglasse obwohl `file .value_required` ist.
