What i mean, each property should be contained in the class declaration before
it's actually defined in construct :)

I really hope we won't turn php into javascript :) Please take a look, the
sugar you
talk about is possible with the following
class Props {
function __construct(array $argv) {
foreach($argv as $arg => $val) {
$this->$arg = $val;
}
}
}
$u = new Props(['hello' => 'world',
'good' => 'bye',
'obj' => new Props(['my' => 'god'])]);
Or even use func_get_args() to make $argv optional.
However this is a VERY bad style. Every object property should be defined with
the
class.

Just forgot to mention one more readability advantage:
It would support "nested" initializations, like it is now possible with arrays
full of strings
$object = new Object({
Property: $aValue,
Property2: $aValue2,
Subobject: new Object({
...
})
});

Of course its working, this is not about a bug but about sleekness and
PHP-to-programmer support ;-)
These assignment-lists are really lengthy and contain too many repetitions.
Its more like requesting the ternary operator instead of the "old" if ... then
... else ...

So object literals. Getting to use names instead of strings.
Meanwhile
$object = new Object();
$object->StringMember = "content";
// etc
doesn't work?

I view as a strength of PHP, not having to declare all fields in a class. For
example think of a class representing a HTML DOM element, like a link. It allow
many fields, but most often you will only use some of them, like "href" or
"class".
In my opinion the best syntax to write is something like:
$link = new Link(href: "target.html", class:"btn btn-info");
At the moment I use arrays:
$link = (new Link)->assign("href" => "target.html", "class" => "btn btn-info");
But the fields in the strings are messy and un-recognizeable.
Phpdoc is far too cluttering. Declaring every possible option is pointless for
some classes, especially if they are highly dynamic, like derived from a
database table.
