<pre>Arrow function doesn't raise early semantic errors if we are using 'super/super()', in comparison to the usual function (<a href="https://people.mozilla.org/~jorendorff/es6-draft.html#sec-function-definitions-static-semantics-early-errors">https://people.mozilla.org/~jorendorff/es6-draft.html#sec-function-definitions-static-semantics-early-errors</a>, )
Also If I correctly understand this topic <a href="http://www.ecma-international.org/ecma-262/6.0/#sec-arrow-function-definitions-static-semantics-contains">http://www.ecma-international.org/ecma-262/6.0/#sec-arrow-function-definitions-static-semantics-contains</a>, then arrow function can contain 'super’ as SuperProperty and SuperCall.
At this topic <a href="http://www.ecma-international.org/ecma-262/6.0/#sec-arrow-function-definitions-runtime-semantics-evaluation">http://www.ecma-international.org/ecma-262/6.0/#sec-arrow-function-definitions-runtime-semantics-evaluation</a> said:
"Any reference to arguments, super, this, or new.target within an ArrowFunction must resolve to a binding in a lexically enclosing environment. Typically this will be the Function Environment of an immediately enclosing function. Even though an ArrowFunction may contain references to super, the function object created in step 4 is not made into a method by performing MakeMethod. An ArrowFunction that references super is always contained within a non-ArrowFunction and the necessary state to implement super is accessible via the scope that is captured by the function object of the ArrowFunction."
So for my understanding arrow function can operate by 'super' property and invoke the 'super()' function.
Later if it necessary we can split this issue into two issues for SuperProperty and SuperCall.</pre>
