Hi again !
The important part is that any instantiations and function calls are
evaluated at call-time and not compile time !
So time() would return the timestamp at time of call and not when
compiler first encounters the COOKIE_PARAMS const array. The new params
keyword would make this clear to the compiler

Thanks for the feedback.
Problem with your re-written example is that it works with/depends on
global variables...
I was the code below actually worked:
<?php
const COOKIE_PARAMS = [
"samesite" => "Lax",
"expires_or_options" => time() + 3600, // Let's say time
is 1787047184
"path" => "/",
"domain" => "",
"secure" => false,
"httponly" => true,
];
[...]

Ah, I think I understand now.
What you're proposing is a structure where you can define a value as an
expression, and that expression is only evaluated when the structure is
used (rather than when it's defined).
So, even in a long-lived application, the expires_or_options value would
always be evaluated as `time() + 3600`
If this were to be implemented, I think it would be better to look at
values, rather than defining an entire structure. I can see it being
used for more than parameters.
Something like an IIFE that's invoked when used rather than when defined.
As a side-note, one way to achieve this in current PHP would be to use a
callable:
```php
$params = function() {
return [
"samesite" => "Lax",
"expires_or_options" => time() + 3600,
"path" => "/",
"domain" => "",
"secure" => false,
"httponly" => true,
];
};
fakeSetCookie("testName", "testValue", ...$params());
sleep(2);
fakeSetCookie("testName", "testValue", ...$params());
```
(3v4l refused to save this, probably because it takes too long)
This can also be written using arrow functions:
```php
$params = fn() => [
"samesite" => "Lax",
"expires_or_options" => time() + 3600,
"path" => "/",
"domain" => "",
"secure" => false,
"httponly" => true,
];
```
