Example from README gives different result

Hi. I really like the idea with lave. Im testing out how to use it to let AlaSQL store itself to a string (so we can restore the state again).

First thing I did was to try the example in on the README. But I get a different result from what is described in the README.

First I installed the modules:

npm install lave 
npm install escodegen

then I copy/paste the example from the README and run:

node << EOF          
  var generate = require('escodegen').generate
  var lave = require('lave')

  var a = [function(){}, new Date, new Buffer('A'), global]
  a.splice(2, 0, a)

  var js = lave(a, {generate, format: 'module'})
  console.log(js)
EOF

The result I get is

export default a;

but the expected result in the README is described as

var a = [
    function (){},
    new Date(1456522677247),
    null,
    Buffer('QQ==', 'base64'),
    (0, eval)('this')
];
a[2] = a;
export default a;

escodegen@1.8.0 + lave@1.1.5 on node@5.3.0 + nvm@3.3.12

Any inputs to why I am not getting same results as described in the README?

you shouldn’t need an IIFE anymore, thanks to @fgnass: https://github.com/jed/lave/pull/23

For now, you can run your lave code in an IIFE to prevent this.

Ok - ill try it out.

Any plans on updating the README example?
