title: Using @lang directive als default value of @yield directive in Blade/Laravel
body: <p>Regarding the Laravel documentation, the <code>@yield</code> directive in a blade template can have a default value as second argument. Since I'm developing a multi language site, how is it possible to use the <code>@lang</code> directive as default value?</p>
  
  <p>I've already tried:</p>
  
  <pre><code>@yield('title', @lang('title'))
  @yield('title', lang('title')) 
  </code></pre>
  
  <p>neither of them is working.</p>
