🔗 YAML: The Norway Problem

Haroen Viaene posted this tweet about YAML:

worst part of yaml: https://yaml.org/type/bool.html

The linked-to page contains the documentation on what defines a boolean in YAML, and details that it can be parsed using this regex:

y|Y|yes|Yes|YES|n|N|no|No|NO
|true|True|TRUE|false|False|FALSE
|on|On|ON|off|Off|OFF

The reason to why this is problematic in some cases, is “The Norway Problem” YAML has.
