readable stream implementation in Node.js

gistfile1.txt

var stream  = require('stream');

var s = new Stream;
s.readable = true;


VS:

var stream = require('stream');
var Readable = stream.Readable;
var util = require('util');

function MyReadable(options) {
  if(!(this instanceof MyReadable)) {
    return new MyReadable(options);
  }
  
  Readable.call(this);
}

util.inherits(MyReadable, Readable);
