Added support of ES6 arrow function specific feature, lexical bind of this and no constructor. http://wiki.ecmascript.org/doku.php?id=harmony:arrow_function_syntax
In patch were implemented the following cases:
this - variable |this| is point to the |this| of the function where arrow function is declared. Lexical bind of |this|
constructor - the using of the command |new| for arrow function leads to runtime error
call(), apply(), bind() - methods can only pass in arguments, but has no effect on |this|
