I try to follow the procedure of: https://wiki.php.net/rfc/howto

It seems to me that list() is not clearly specified.
I wanted to know your opinions on this.


For example :
$key =3D "a";
$value =3D 1;
$array =3D [$key =3D> $value];

[$key =3D> $value] =3D $array;

We all agree that now $key =3D 'a' and $value =3D 1

And I wonder why
What happens in this case :

[$key =3D> $value] =3D ['b'=3D>2];

$key =3D 'b' and $value =3D 2 or all is null ?

list() supports destructuring assignment for arrays. Do you have an opinion
on object destructuring ?

*Do you think seeing list() as the reciprocal of a function call is
interesting ?*

Otherwise, how to use a default value, type hinting, nullable/optional
variable... It's not interesting ?

There are many things that could be done with but don't work. For example :

$array =3D [1, 2, 3];
[...$values] =3D [...$array];

My question is: I see list() as the reciprocal of an array(). Do you think
it would be interesting for everyone if I proposed my vision?
