The YAML document from hell

The author shares their opinion and argues that YAML, a data format, is too complicated and full of unexpected behaviors despite its aim to be human-friendly.

They provide an example document to illustrate this point, highlighting features such as sexagesimal numbers, non-string keys, and accidental numbers, that make it difficult to parse or prone to errors.

The author suggests alternative configuration formats such as TOML or JSON with comments or Json with commas and comments and also recommends generating JSON as a better alternative to YAML, using tools like Nix or Python.
