The Closure class

INTRODUCTION
	Class used to represent anonymous functions.

	Anonymous  functions, implemented in PHP 5.3, yield objects of this type. This fact used to be considered an implementation detail, but it
       can now be relied upon. Starting with PHP 5.4, this class has methods that allow further control of the anonymous  function  after  it  has
       been created.

	Besides the methods listed here, this class also has an __invoke method. This is for consistency with other classes that implement calling
       magic, as this method is not used for calling the function.
