 # libyaml 0.2.1 removed the erroneously written document end marker (`...`) after some scalars in root context (see https://github.com/yaml/libyaml/pull/18).
 # Earlier libyaml releases still write the document end marker and this is hard to fix on Crystal's side.
 # So we just ignore it and adopt the specs accordingly to coincide with the used libyaml version.
