PHP Bug Type: Feature/Change Request
Bug description: Closures returned by functions/methods must be stored to be
executed...
Description:
------------
When returning an anonymous function from a method or function call, the
returned closure is not directly executable in a logical fashion. The
closure needs to be stored in order to be executed or must be called via
the call_user_func family of functions.
This is fairly illogical and inconsistent with the idea of closures.
Reproduce code:
---------------
function test($a)
{
return function($b) use($a) { echo $a . ':' . $b . '<br/>'; };
}
call_user_func(test(1), 2);
$x = test(1);
$x(2);
test(1)(2);
Expected result:
----------------
Output should be:
1:2
1:2
1:2
Actual result:
--------------
Execution fails. Error:
PHP Parse error: syntax error, unexpected '('
