A JavaScript equivalent of PHP's forward_static_call

{% codeblock funchand/forward_static_call.js lang:js https://raw.github.com/kvz/phpjs/master/functions/funchand/forward_static_call.js raw on github %}
function forward_static_call (cb, parameters) {
  // http://kevin.vanzonneveld.net
  // +   original by: Brett Zamir (http://brett-zamir.me)
  // %          note 1: No real relevance to late static binding here; might also use call_user_func()
  // *     example 1: forward_static_call('isNaN', 'a');
  // *     returns 1: true

  }
