[Moo] Getting the first index of an object

[rpflo]

So if I've got:

var object={
        foo:{},
        bar: {},
        baz: {}
}

How would I ...

var first = object[0];
console.log(first);

Obviously that doesn't work because the first index is named "foo",
not 0.

I've messed around with $pick and $arguments, but can't figure it out.

There's probably a very simple non-moo way to do this, but I'm hardly
versed in "real" javascript--to my own detriment for sure.

Thanks!
