Yes, I know. My point is that 1018 motivated 1040: 1018 replaced 
postblits with copy constructors, and 1040 replaces `opPostMove` 
with move constructors for consistency. And I didn't say that 
1040 has been accepted, I said 1014 was accepted. And regarding 
1040, I said "we're hoping the collaboration here will result in 
a stronger DIP for the next review round."

As far as I know, they aren't yet implemented. The changelog for 
2.088.1 says nothing about it. So yes, that looks like it's 
incorrect. I hadn't noticed that before.

You're welcome.
