It's almost certainly bad code anyway. The free function version of opEquals
specifically does extra work to make equality checks correct and avoids some of
the pitfalls that opEquals causes in Java (e.g. doing comparison in both
directions if the types aren't identical). So, if we break that, it's probably
a _good_ thing. And if they _really_ want to do that, that can still do it
with their derived classes which define opEquals. They just can't do it with
Object.
