Fogus: Node.js should become its own language(blog.fogus.me)

  d = long_io_operation()
  d.addCallback(callback)
  d.addErrback(errback)

   try:
       result = yield long_io_operation()
       callback(result)  
   except Exception, e:
       errback(e)

    Javascript itself has very few faults.

    foo = function(){
        var bar=0
        return function(){
            bar=bar+1
            return bar
        }
    }
    baz=foo()

    baz() // => 1
    baz() // => 2
    baz() // => 3
    bar;  // => ERROR: bar is not defined

    async.waterfall(
      [ function (callback) {
          // do thing 1
          callback();
        }
      , function (callback) {
          // do thing 2
          callback();
        }
      , function (callback) {
          // do thing 3
          callback();
        }
      ]
      , function (error) {
          if (error) {
            // ohnoes errors
          }

          // all done!
        }
      );
