Feature request: allow custom object container class during decode

[yairlenga]

While looking through the code, I noticed that _object() already appears to support constructing object containers other than plain hashes.

Would it make sense to expose this through the public API?

Use cases include:

• preserving key order
• integrating with modules such as Hash::Ordered or Tie::IxHash
• using custom mapping classes

For example, an API could look something like:

Sample implementation:

my $json = JSON->new
    ->object_class('Hash::Ordered');

my $obj = $json->decode($text);

Unless I'm missing something, part of the implementation may already be present internally, but there does not appear to be a public option to select the object container class.

Would you be interested in such a feature?
