+
+    MemberExpression:
+      MemberExpression . PrivateName
+
+    Static Semantics: AllPrivateIdentifiersValid
+      AllPrivateIdentifiersValid is an abstract operation which takes names as an argument.
+
+      MemberExpression : MemberExpression . PrivateIdentifier
+        1. If StringValue of PrivateIdentifier is in names, return true.
+        2. Return false.
+
+      ClassBody : ClassElementList
+        1. Let newNames be the concatenation of names with PrivateBoundIdentifiers of ClassBody.
+        2. Return AllPrivateIdentifiersValid of ClassElementList with the argument newNames.
+
+    Static Semantics: Early Errors
+
+    ScriptBody : StatementList
+      It is a Syntax Error if AllPrivateIdentifiersValid of StatementList with an empty List as an argument is false unless the source code is eval code that is being processed by a direct eval.
