+Subject: Adjust tests to reflect OpenStruct changes on Ruby3.0
+
+Ref.: https://github.com/ruby/psych/issues/540
+
+OpenStruct on Ruby3.0 changed its marshalling/unmarshalling code,
+which is now impacting safe_yaml's testcase.  The two adjustments that
+needed to be made are:
+
+- OpenStruct's instance_variable_get will now symbolize its hash keys,
+  instead of using strings.
+
+- OpenStruct's to_yaml method will not output the 'table' entity
+  anymore.
