Thank you for your RFC.

I find it not obvious at all that:

- Non-(string|int) path segments will result in the default value being 
returned, rather than a TypeError being thrown or just proceeding with 
implicit coercion.
- Encountering a non-array value along the path will result in the 
default value being returned, rather than an Exception being thrown. 
Returning a default value for an existing path element that is not an 
array feels like a source of error, particularly when any intermediate 
value is an object implementing ArrayAccess.

I would expect the following to hold:

     $path = ['foo', 'bar', 'baz'];
     array_get($array, $path) === array_get(array_get($array, 
array_shift($path), []), $path);

which it will not due to (2).

And the further looking at the examples:

     $array = /* … */;

     array_has($array, ['product', 'name']);
     array_has($array, ['product', 'color']);

Just looking at the code without knowing what the function does, I 
probably would have expected it to be either:

1. `in_array()` operating on multiple values that all need to be there.
2. `array_key_exists()` operating on multiple keys that all need to be 
there.

But not a “path through the array”.
