static variables must be initialized with constant values. Closures are expressions.

Description:
------------
Distro: openSUSE Leap 42.1 (x86_64)

Packages used: php7-7.0.15-35.2.x86_64

Standard (not changed) php.ini

Command to run: php test-static-lambda.php


Test script:
---------------
<?php
function f1() {
  $lambda1 = function() {};  // line 3
}

function f2() {
  $lambda2 = static function() {};  // line 7
}

function f3() {
  static $lambda3 = function() {};  // line 11
}

function f4() {
  static $lambda4 = static function() {};  // line 15
}


Expected result:
----------------
Lines 11 and 15 should not produce a fatal error. BTW, I'm slightly in doubt about line 11
since it looks wrong.

Instead, lines 11 and 15 should be performed silently as lines 4 and 9 do.

Actual result:
--------------
PHP Fatal error:  Constant expression contains invalid operations in
/home/user/tmp/test-static-lambda.php on line 11

If you comment out the line 11 then:

PHP Fatal error:  Constant expression contains invalid operations in
/home/user/tmp/test-static-lambda.php on line 15
