Description:
------------
It's not possible to make use of variable aliasing in PHP when the alias is
used
within the use clause of a lambda function construct that is assigned to that
variable (recursion).
PHP denies to do what it is commanded with a Fatal error: Cannot destroy active
lambda function. But the function is not destroyed. It's just not that the
variable container contains the identifier of it.
I'd like to change that, and I don't want to waste another variable name. Also
I
don't understand how I can actually destroy something I should not have any
access
to from PHP userland.
Or if that is intended, please allow us to destroy the active lambda making the
function return NULL and continue to execute.
Test script:
---------------
$f = function() use (&$f) {
$f = function() {echo "hello"};
};
$f();
$f();
Expected result:
----------------
hello
Actual result:
--------------
Fatal error: Cannot destroy active lambda function
