The post discusses challenges with YAML, particularly in relation to the PyYAML library's limitations when using the YAML 1.1 standard. Users express frustration over PyYAML's lack of support for YAML 1.2 and note that while PyYAML is still functional for YAML 1.1, alternatives like ruamel.yaml provide better compatibility for modern standards. The article highlights a specific issue where the full YAML 1.1 schema produces unexpected behavior, suggesting a workaround using BaseLoader to interpret content as strings instead.
