arrow functions: no line break between params and =>

input

module.exports = function() {
    var f = x
        => 2;
    return f();
};

generated

module.exports = function() {
  return 2;

expected: should be compile error

arrow functions: no "prototype" and "name" properties

input

module.exports = function() {
        var a = () => 5;

};

generated

module.exports = function() {
  var a = function() {
    return 5;

expected: arrow functions should have no "prototype" and "name" properties
