I like this concept, but instead of introducing a new syntax, have you

I think the intent would be clearer and it would avoid introducing a new syntax.
Indeed, except that I think it should be better to have *by default* the same
behaviour between built-in functions and user-defined functions:
```php
function foo() { }
foo(42);
// in PHP 8.x: Deprecated: foo() expects expects exactly 0 arguments, 1 given
// in PHP 9: Fatal error: foo() expects expects exactly 0 arguments, 1 given
```
and, in case you want a variadic function:
```php
#[Variadic]
function foo() { }
```
Alternatively, we don’t really need to introduce a new attribute, because one
can just write:
```php
function foo(...$args) { }
```

Hello Claude,
I strongly agree in theory, but this could break existing code, and
moreover such a proposal was already rejected:
