Description:
------------
The complex string syntax will not include static classes. I cannot use them as output.

Quote from doc: In fact, any value in the namespace can be included in a string with this syntax. Simply write the expression the same way as it would appear outside the string, and then wrap it in { and }. 

I do expect this to be wrong. The documentation states "any value" and A::$a is a valid value for a string.


Reproduce code:
---------------
class A {
  static public $a = 'A';
}

echo "{A::$a}";

Expected result:
----------------
A

Actual result:
--------------
{A::}
