Are you sure on your bet?
lib.php:
<?php
declare(strict_types = 1);
function foo(int $a) {
// no function call here
}
?>
The declare here does just nothing.
a.php:
<?php
require "lib.php";
foo("123"); // will work
?>
b.php:
<?php
declare(strict_types = 1);
require "lib.php";
foo("123"); // will give an error
?>
This behavior is unacceptable.
Caller (a.php, b.php) must satisfy lib.php expectation to make lib.php
work as it should. Otherwise, all kinds of unexpected for lib.php and it's
users may happen.
