Subject: [RFC] Using objects as keys
From: smalyshev@gmail.com (Stas Malyshev)

Hi!

I would like to present to your attention an RFC about using object as keys:

https://wiki.php.net/rfc/objkey

It was discussed in the past on the list:
http://marc.info/?t=141145969600001&r=1&w=2
and I think it makes sense to propose a formal RFC for it. Both the text
and the code in the patch includes bits done by myself and Joe Watkins.
The patch does not cover 100% of cases but should work for most
reasonable scenarios, if something is wrong or you have ideas how to
make it better please tell.

The name __hash is not final, I am open to using __toKey instead or any
reasonable alternative, we may also include a couple of options in the
vote if that will be a point of disagreement.

Thanks,
Stas
