Hi I was trying out this library and following one of the simple examples from the read me and its throwing an error.

Heres my script.

var Trait = require('trait');

var t = Trait({
  foo: Trait.required,
  bar: function bar () {
    return this.foo;
  },
  baz: 'baz'
});

And heres the error

/Users/kevzettler/VoxLords/node_modules/trait/index.js:238
        attr._origin = attr.value;
                           ^

should be
var Trait = require('simple-traits');
