 * When the Function constructor is called with arguments p, body the following steps are taken:
 * i) Let Result(i) be the first argument
 * ii) Let P be ToString(Result(i))
 * iii) Call ToString(body)
 * iv) If P is not parsable as a FormalParameterList_opt then throw a SyntaxError exception
 * v) If body is not parsable as FunctionBody then throw a SyntaxError exception
 * vi) Create a new Function object as specified in 13.2 with parameters specified by parsing P as a FormalParameterListopt and body specified by parsing body as a FunctionBody
 * Pass in a scope chain consisting of the global object as the Scope parameter
 * vii) Return Result(vi)
