+    Runtime Semantics: ClassDefinitionEvaluation
+
+    ...
+    27. For each ClassElement e in order from elements
+      a. If IsStatic of me is false, then
+        i. Let fields be the result of performing ClassElementEvaluation for e with arguments proto and false.
+      b. Else,
+        i. Let fields be the result of performing ClassElementEvaluation for e with arguments F and false.
+      c. If fields is an abrupt completion, then
+        i. Set the running execution context's LexicalEnvironment to lex.
+        ii. Set the running execution context's PrivateNameEnvironment to outerPrivateEnvironment.
+        iii. Return Completion(status).
+    ...
+
+    Runtime Semantics: ClassElementEvaluation
+
+    ClassElement: FieldDefinition;
+      Return ClassFieldDefinitionEvaluation of FieldDefinition with parameter false and object.

+    Runtime Semantics: ClassFieldDefinitionEvaluation
+      With parameters isStatic and homeObject.
+
+    1. Let fieldName be the result of evaluating ClassElementName.

+    Runtime Semantics: Evaluation
+      ComputedPropertyName: [ AssignmentExpression ]
+
+    1. Let exprValue be the result of evaluating AssignmentExpression.
+    2. Let propName be ? GetValue(exprValue).
+    3. Return ? ToPropertyKey(propName).
