I'll bite.

    ```
    >>> (bool)"1";
    => true
    
    >>> (bool)"0";
    => false
    
    >>> (bool)"false"
    => true

```

(there are plenty of other things like that; the default call-by-value is also unexpected)

Also: Laravel has plenty of "magic" ie things are intercepted via runtime reflection and then rerouted into something that hopefully "does-the-right-thing". It obfuscates control flow, causes unexpected side-effects and confuses IDEs and developers alike.

Even the popular frameworks have combinations of subawesome code and silly ideas. Just the latest example I ran into:

    ```
    int append(string $path, string $data) /* the signature of the Filesystem facade */    

    /* the implementation in FilesystemAdapter: */

    public function append($path, $data, $separator = PHP_EOL)
        {
            if ($this->fileExists($path)) {
                return $this->put($path, $this->get($path).$separator.$data);
            }

            return $this->put($path, $data);
        }

    ```

    - It's not correct as it will add (ffs why?) a newline in between the files.
    - Performance wise, this is bloody awful.
    - however, you *can* specify the separator in any call as the facade interface is just documentation and is bypassed via reflection (but that confuses your IDE)
