For static analysis, though, unary predicate (e.g. `is_list()`) is much
easier to work with, secondary only to actual type. Flags may lead to
indirection, such as (contrived example)
```php
class C {
const FLAGS = ZERO_INDEXED | ASSOCIATIVE;
private function getFlags(): int {
return static::FLAGS;
}
public function foo(array $array): void {
if (is_array($array, $this->getFlags())) { ... }
}
```
