Subject: [RFC][DISCUSSION] Object type hint, now with added variance
From: danack@basereality.com (Dan Ackroyd)

Hi,

This is the reintroduction of the Object Type RFC for discussion.

There was previously strong feedback from people who would prefer that
the inheritance checks for methods that use object types should be
co/contravariant. This has been added to the RFC.

https://wiki.php.net/rfc/object-typehint

cheers
