PHP has several ways to perform casting:
1. (int) $foo
2. settype($foo, 'int');
3. intval($foo)
They are occasions where the programmer will prefer one method to the other.
For example:
1. foo((int) $bar)
2. settype($someNonTrivial[$expr]['ession'], 'int');
3. array_map('intval', $foo)
The `intval($foo)` family of functions might be replaced by `function ($foo) {
return (int) $foo; }` (or maybe soon by `fn($foo) => (int) $foo`), so that it
might not be a necessity to double them with `intvalIfNotNull($foo)`, etc.
functions (also, finding a good name is not evident). But as for `settype()`,
it cannot be replaced by casting syntax in case the target type is not written
literally in source code; so that we should continue to fully support it. (And
