PHP written in a JavaScript style is already possible with PHP 5.3. I started a little thread about this on a forum but didn't get that much feedback: http://www.sitepoint.com/forums/showthread.php?t=565576 It's not really what we're used to in JavaScript but it's very close.

This gives a fatal "Call to undefined method DateTime::getAtom()"
    $d = new DateTime();
    $d->getAtom = Curry::create(array($d, 'format'), DATE_ATOM);
    echo $d->getAtom();
     
This is the same as the following: $obj = new stdClass(); $obj->method = function() {
    return "foo";
}; $obj->method(); The first "method" is a property, the call to "method" is - well - a method call. Because PHP separates methods and properties in the class entry structure - and because we have magic methods like __set, __get and __call, there is no efficient and logical way how to search for properties with closure instances when a method is not found. We discussed that before and decided to let closures go out into the wild and think about adding a solution for prototype alike inheritance later. cu, Lars
