Hi Larry!
I have a lot of respect for the vision you're working on. Great
advances sometimes come out of great visions.
But let's not forget that so far it's only a vision and not all
visions come to fruition. We don't know - at the moment it's anybody's
guess.
At this point I hardly expect you

The current RFC text is not consistent with using `=` or `=>` for the
assignments. The assignment `=` is vastly more common, though, and I
don't understand why if we are using an array syntax we aren't using
`=>`.
I intend to vote no. I agree that we need to do something in this
space, but this

I really like the suggested "with" syntax, - in fact I had
contemplated something like that along the way.
The slight "problem", I think, is that, as you mention, adding

Hi again,
Since
I just realized that syntax C and D as proposed - without anything to
signify end of COPA - become really awkward when writing nested COPA:
$foo->
a = 1,
b = 2,
c = (new Foo)->
a = 3,
b = 4,.

How do we indicate that the nested block ends and jump back to the
Hi Andrea, thanks for your feedback.
Let's talk about syntax then :-)
The currently suggested syntax is

The can be an existing object:
$foo->[a = 1];
Or a new, yet anonymous, object:
(new Foo)->[a = 1];

I don't think it's conflicting _if you insist on brackets_ after the new
expression. PHP Parser grammar for "new" expressions is
T_NEW class_name_reference ctor_arguments
If you allowed the shorter syntax, ctor_arguments would allow an
object_properties entry.

That's ok, square brackets are usually related to arrays and what I
want is something similar to array literals.

Hey Jakob,
What happens if you have an expression that throws?
class Foo
{
public $a;
public $b;
public $c;
}
$instance = new Foo();
function iThrow() {

}
try {
$foo ->[
a = 'a',
b = iThrow(),
c = 'c',

Sorry to say but the syntax look very un-PHP-like.

I love the idea!
The syntax for new objects looks a little verbose – would it be possible to
use
$foo = new Foo()[
property1 = "hello",
property2 = 5,
];
as an alternative to
$foo = (new Foo())->[
property1 = "hello",
property2 = 5,
