Hello,

Following the RFC process, I'= ;m sending this to propose a PHP change. More precisely a new zend language= token.=C2=A0

This is somehow linked to the recently acc= epted RFC called "new MyClass()->method() without parentheses"= , the goal is to introduce a shorthand for the "new" keyword.=C2= =A0

Motivations :
The new keyword= sometime has a bad DX, for example when chaining Class instantiation like = this :
$foobar =3D new Foo( new Bar(), new Etc());

=
We can quickly have very long class object construction in some = case.=C2=A0

In lot of Framework, to improve DX, st= atic function construct are often used to avoid the new keyword, some creat= e additional object builders, etc.

As a first try,= I start updated code to completely make the new keyword optional, like in = Dart language for example, but it require very big change, with lot of impa= ct (collision with function).=C2=A0

So here is=C2= =A0my proposal :=C2=A0

Add a "new"= ; shorthand, using the tilde character : "~"
I made a P= OC, and it works well, declaring a new language token=C2=A0T_SHORT_NEW that= simply reuse=C2=A0ZEND_AST_NEW under the hood.=C2=A0

<= div>Here are some example of what it may look like for userland, through so= me tests I wrote :=C2=A0
--TEST--
New keyword shorthand
--FILE--
<?php
 class A {
     public function b() {
          echo "I'm B";
     }
 }

 ~A()->b();

?>
--EXPECT--
I'm B=
Other with nested :=C2=A0

<= div style=3D"color:rgb(8,8,8)">
--TEST--
=
New keyword shorthand encapsulation
=
--FILE--
<?p=
hp
class Foo {<=
br>    public func=
tion __construct(
        public string $name
    ) {}
}
class Bar {
   public function _=
_construct(
   =
     public Foo $foo
   ) {}
}=


 $bar =3D ~Bar(~Foo("I&=
#39;m foo in bar"));
 echo $bar->foo->name;

?>
--EXPECT--I'm foo in bar
As a last word, just want= ed to add it will work on nested Attribute too, so for example this nested = Attribute used in Doctrine :=C2=A0

#[AttributeOver= rides([
=C2=A0 =C2=A0 new AttributeOverride(
=C2=A0 =C2=A0 =C2=A0 =C2= =A0 name: "id",
=C2=A0 =C2=A0 =C2=A0 =C2=A0 column: new Column= (name: "guest_id", type: "integer", length: 140)
=C2= =A0 =C2=A0 ),
=C2=A0 =C2=A0 new AttributeOverride(
=C2=A0 =C2=A0 =C2= =A0 =C2=A0 name: "name",
=C2=A0 =C2=A0 =C2=A0 =C2=A0 column: n= ew Column(name: "guest_name", nullable: false, unique: true, leng= th: 240)
=C2=A0 =C2=A0 )]
)]

Will also w= ork like this :=C2=A0
#[AttributeOverrides([
=C2=A0 =C2=A0 ~At= tributeOverride(
=C2=A0 =C2=A0 =C2=A0 =C2=A0 name: "id",
= =C2=A0 =C2=A0 =C2=A0 =C2=A0 column: new Column(name: "guest_id", = type: "integer", length: 140)
=C2=A0 =C2=A0 ),
=C2=A0 =C2= =A0 ~AttributeOverride(
=C2=A0 =C2=A0 =C2=A0 =C2=A0 name: "name&quo= t;,
=C2=A0 =C2=A0 =C2=A0 =C2=A0 column: new Column(name: "guest_nam= e", nullable: false, unique: true, length: 240)
=C2=A0 =C2=A0 )])]

About implementation, it should'n have= any impact on SAPI or extension, the new keyword will still exist, it'= s just a new shorthand.

I think you get the p= oint, is it something that some of you would be interested in? I would be h= appy to make a proper RFC proposal.=C2=A0

Just reg= istered a wiki account : benconda

Thank you,=
