Dynamic attribute setters

[danwrong]

Default or given attributes can be a function that gets evaluated at initialize time in the context of the component for dynamic attr setting.

this.attributes({ 
   href: function() {
    return this.$node.attr('href');
  }
});

but you can also do it at attach time:

Tweet.attachTo('.tweet', {
  tweetId: function() { return this.$node.data('tweet-id') }
});

SICK!

Like it. Needs documentation?

I like. Is there a risk that a flight client's legacy code might include function attrs that they didn't intend to be evaluated?

[danwrong]

Was intending to update with docs if people liked the idea.

Re legacy: This only works for this.attributes so shouldnt be too much of an issue.

[tgvashworth]

Let's make sure we get this documented.
