Hi internals,

I would like to present a draft RFC for allowing object keys in arrays:
https://wiki.php.net/rfc/object_keys_in_arrays

The specification in the RFC is incomplete, and primarily focussed on what
impact this has from an internal perspective.
https://github.com/php/php-src/pull/6588 is a draft implementation that
illustrates the necessary changes.

The primary motivation, and reason why I am looking into this now, is that
the current enum proposal is based on objects, and I consider it somewhat
important that enum values can also work as array keys.

From a technical perspective, this also lays the groundwork for supporting
other key types in the future, e.g. if we wish to switch PHP to use
arbitrary-precision integers.

Regards,
Nikita
