V8 Optimizations

V8 will not define variables that would normally be within JS function scope until they're actually called.

test('visiting /foo/bar', function(assert){
  var foo = server.create('foo');
  var bar = server.create('bar');

      var someProp = foo.callProperty;

When the console opens, foo will be in scope, while bar will be undefined
