Description:
------------
Just a small nitpick about PHP's error reporting that I thought I'd file for completeness' sake.

PHP currently says "exactly N expected" instead of "at least N expected" for functions using the ... splat/scatter operator.

[I'm not seeing an existing bug for this, based on searches for "exactly" and "expected".]

Test script:
---------------
$ php8.0 -r 'function a($a, $b, ...$c) {} a(1);'
PHP Fatal error:  Uncaught ArgumentCountError: Too few arguments to function a(), 1 passed in ... line 1 and exactly 2 expected in ...:1


Expected result:
----------------
My suggestion:

PHP Fatal error:  Uncaught ArgumentCountError: Too few arguments to function a(), 1 passed in ... line 1 and at least 2 expected in ...:1


Actual result:
--------------
As noted
