+  PrivateFieldGet (P, O)
+    1. Assert: P is a Private Name.
+    2. If O is not an object, throw a TypeError exception.
+    3. If P.[[Kind]] is "field",
+      a. Let entry be PrivateFieldFind(P, O).
+      b. If entry is empty, throw a TypeError exception.
+      c. Return entry.[[PrivateFieldValue]].
+    4. Perform ? PrivateBrandCheck(O, P).
+    5. If P.[[Kind]] is "method",
+      a. Return P.[[Value]].
+    6. Else,
+      a. Assert: P.[[Kind]] is "accessor".
+      b. If P does not have a [[Get]] field, throw a TypeError exception.
+      c. Let getter be P.[[Get]].
+      d. Return ? Call(getter, O).
+
+  ClassElementName : PrivateIdentifier
+    1. Let privateIdentifier be StringValue of PrivateIdentifier.
+    2. Let privateName be NewPrivateName(privateIdentifier).
+    3. Let scope be the running execution context's PrivateEnvironment.
+    4. Let scopeEnvRec be scope's EnvironmentRecord.
+    5. Perform ! scopeEnvRec.InitializeBinding(privateIdentifier, privateName).
+    6. Return privateName.
+
+  MakePrivateReference ( baseValue, privateIdentifier )
+    1. Let env be the running execution context's PrivateEnvironment.
+    2. Let privateNameBinding be ? ResolveBinding(privateIdentifier, env).
+    3. Let privateName be GetValue(privateNameBinding).
+    4. Assert: privateName is a Private Name.
+    5. Return a value of type Reference whose base value is baseValue, whose referenced name is privateName, whose strict reference flag is true.
