hi, would be nice having this syntax for closures


$this->addResult
(
    (
        function ($param) use ($x) { return $x*$param; }
    )($result)
);

a closure defined and executed in the same instruction, as JavaScript allows

I belive stas' had a patch for this? Or atleast function call chaining, but I assume if implemented it would allow this syntax?
 [2010-08-17 22:41 UTC] giorgio dot liscio at email dot it 
any alternative syntax can be good if the result is the same, defining end invoking on the same instruction without using any var

now:

$f = function($x) use($y){return $x * $y;};
$f(22);

request:

(function($x) use($y) {return $x * $y;})(22);

or

function($x) use($y) {return $x * $y;}(22);

or 

function($x) use($y) invoke(22) {return $x * $y;};

etc

I like the:
function($x) use($y) {return $x * $y;}(22);

approach, its consistent with that of other languages, like JavaScript

Implemented by https://wiki.php.net/rfc/uniform_variable_syntax in PHP 7. Parentheses around the closure are required.
