Source/JavaScriptCore:
'super' and 'super()' inside of the arrow function should lead to syntax error if they are used
out of the class context or they wrapped by ordinary function. Now JSC returns ReferenceError but
should return SyntaxError according to the following specs:
http://www.ecma-international.org/ecma-262/6.0/#sec-function-definitions-static-semantics-early-errors
and http://www.ecma-international.org/ecma-262/6.0/#sec-arrow-function-definitions-runtime-semantics-evaluation
Curren patch implemented only one case when super/super() are used inside of the arrow function
Case when super/super() are used within the eval:
class A {}
class B extends A {
costructor() { eval("super()");}
}
is not part of this patch and will be implemented in this issue https://bugs.webkit.org/show_bug.cgi?id=153864.
The same for case when eval with super/super() is invoked in arrow function will be
implemented in issue https://bugs.webkit.org/show_bug.cgi?id=153977.
