It seems like something similar could be done with custom types.

$result = $mapper->denormalize($value, 'unwrap{path: "[baz][inner]", ...<ValueType>}');

On the other hand, this is not very correct from a semantic point of view...

I'm not sure that this is a critically needed functionality. Often, such things are solved manually.

The only downside is that the mapper does not yet support array shapes, otherwise we could do:

$json = '{"baz": {"foo": "bar", "inner": {"title": "value", "numbers": [5,3]}}}';

$result = $mapper->denormalize(json_decode($json), <<<'TYPE'
    array{ 
        baz: array{
            inner: ExpectedType, 
            ...
        }
    }
    TYPE);

/** @var ExpectedType $value */
$value = $result['baz']['inner'];

For some reason it just seems to me that this is some kind of separate, full-fledged functionality that should be introduced along with embeddable (Doctrine-like) types. The only difference is in the unpacking: One (embeddables) puts data it inside other type, and the other (unwraps) outside.

P.S. If there are any suggestions on how to elegantly solve the problem - welcome))) I can only theorize for now.
