Bug 153977 – [ES6] Arrow function syntax. Using eval with 'super'/'super()' in arrow function within the class should not lead to Syntax error

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: JavaScriptCore

Using eval with 'super'/'super()' in arrow function within the class should not lead to Syntax error:

const testValue  = 'test-value';

class A {
    constructor() {
        this.idValue = testValue;
    }
};

class B extends A {
  constructor (beforeSuper) {
      var arrow = () => eval('(() => super())()');
      arrow();
  }
};

let b = new B();
b.idValue == testValue; //true

There is 15.1 https://tc39.github.io/ecma262/#sec-scripts-static-semantics-early-errors that stats:
ScriptBody:StatementList
#It is a Syntax Error if StatementList Contains super unless the source code containing super is eval code that is being processed by a direct eval that is contained in function code that is not the function code of an ArrowFunction.
#It is a Syntax Error if StatementList Contains NewTarget unless the source code containing NewTarget is eval code that is being processed by a direct eval that is contained in function code that is not the function code of an ArrowFunction.
