      8 info: |
      9    6. If IsAnonymousFunctionDefinition(AssignmentExpression) is true, then
     10       a. Let hasNameProperty be HasOwnProperty(propValue, "name").
     11       b. ReturnIfAbrupt(hasNameProperty).
     12       c. If hasNameProperty is false, perform SetFunctionName(propValue,
     13          propKey).
