title: Using Nodejs unstable alongside stable to access ES6/Harmony
body: <p>I wanted to start practicing ES6, and plan to do that using Node.js (--harmony) in the first instance. I have the stable 0.10 branch on my Ubuntu computer already and want to run the unstable version just for testing new coding styles.</p>
  
  <p>Is there a way of running a node 0.11 instance locally to a project (i.e. from node-modules?), or some other best practice?</p>
  
  <p>Or, as this is a development machine anyway, perhaps I could just replace stable Node with unstable anyway as it is now 'stable enough'?</p>
