-;; YAML-Parser: liest eine Teilmenge von YAML (Block-Syntax, keine
-;; Flow-Collections, keine Block-Skalare) in verschachtelte
-;; alist/list-Strukturen. Gegenstück zu yaml_writer.scm.
-;;
-;; Ergebnisformat:
-;;  - Mapping -> alist mit String-Keys, Reihenfolge wie in der Datei
-;;  - Liste   -> Liste (auch als "- key: value"-Inline-Mappings)
-;;  - Skalare -> String, Zahl, #t/#f, '() (null / {} / [])
-;;
-;; Skalar-Interpretation:
-;;  - unquoted und 'single-quoted' Werte werden interpretiert
-;;    (Zahl, true/false/null). Das Interpretieren von single-quoted
-;;    Werten ist Kompatibilitätsverhalten zum alten Parser:
-;;    authors.yml notiert Zahlen als '1898'.
-;;  - "double-quoted" Werte bleiben immer Strings; \\, \" und \n
-;;    werden entescaped (so schreibt sie der yaml_writer).
-;;  - Kommentare (#) werden nur außerhalb von Quotes entfernt und nur,
-;;    wenn ihnen ein Leerzeichen oder der Zeilenanfang vorausgeht.
