Thanks!

This was done to more-or-less mirror the behavior from `objc_direct`. Though if 
people think the implementations should differ I'm cool with that.

Yea sure, whatever the correct process is I'm more than happy to cooperate. I 
was going to post something on the mailing list some time this week, but this 
diff got attention early! What would be the best way to start that conversation?

Yea, the naming I'm not too happy about and changed it around a few times. Your 
proposed naming is certainly more clear.
