Latest attempt to templatize the free function opEquals (which is not a full
fix for this but is the first step in the process):

Issue 9769 depends on issue 12537, which changed state.

Relevant discussion on how to transition away from having these functions on
Object (the thread got broken up a bit - probably by the mailman bug):

http://forum.dlang.org/post/mailman.214.1369617617.13711.digitalmar...@puremagic.com
http://forum.dlang.org/post/mailman.280.1369712394.13711.digitalmar...@puremagic.com

The key suggestion is to change the compiler so that those 4 functions can be
free functions in object_.d, similar to how the compiler already does special
stuff for == rather than simply calling Object's opEquals.

Was there a conclusion on how this will affect backwards compatible?

No, other than the fact that we'd probably have to keep the functions on
opEquals for a while as part of the transition. I expect that the steps will be
something like

1. Convert everything over in druntime so that those functions don't have to be
on Object.

2. Deprecate the functions on Object.

3. Remove the functions from Object.

I expect that it'll take quite a while to go through those stages though, and
it may be the case that we'll be forced to remove them from Object faster than
we'd like due to some implementation issue that makes it so that keeping it
around is a problem; I don't know. Regardless, the first step is making those
functions on Object unnecessary, and that's going to take a while (primarily
due to AAs).
