为什么我的Blade模板内容会显示两次？

I'm having trouble with my blade templates. For some reason, I get the content of my view printed out twice, once by the yield where I would expect but also another time before the view that is extended performs any action.

My route is:

Route::get('/', array('as' => 'home', function () {
    return View::make('default');
}));

The default view (default.blade.php) is this:

@extends('test')

@section('title')
    Default
@show

@section('content')
    <p>Content goes here<p>
@show

And the test view (test.blade.php) is this:

<h1>Anything above should be be there!</h1>
<h3>@yield('title')</h3>
@yield('content')

And this generates:

Default
<p>Content goes here<p>
<h1>Anything above should be be there!</h1>
<h3>Default</h3>
<p>Content goes here<p>

Try

@extends('test')

@section('title')
    Default
@stop

@section('content')
    <p>Content goes here<p>
@stop

Shouldnt this be...@stop instead of @show

@extends('test')

@section('title')
Default
@stop

@section('content')
<p>Content goes here<p>
@stop
