Description:
------------
Either new \MyClass($foo->getBar()) is used or new $class($foo->getBar()) is used. If the instanciated class has no constructor explicitly defined or inherited, $foo->getBar() will never be invoked. This prevent any side-effect to be run and can produce very unexpected behaviour.

This should either be fixed so the arguments are ALWAYS evaluated, or documented as such.

CF example belows

Test script:
---------------
<?php

class foo { public $i = 0; function createANewBar() { ++$i; return null; } }

class no_construct { }

class a_construct { public function __construct() { } }

$myFoo = new foo;

echo $myFoo->i.PHP_EOL;

$class = 'no_construct';

$object = new $class($myFoo->createANewBar());

echo $myFoo->i.PHP_EOL;

$object = new no_construct($myFoo->createANewBar());

echo $myFoo->i.PHP_EOL;

$class = 'a_construct';

$object = new $class($myFoo->createANewBar());

echo $myFoo->i.PHP_EOL;

$object = new a_construct($myFoo->createANewBar());

echo $myFoo->i.PHP_EOL;
