afaik that's RVO, isn't it?
D's RVO semantics are pretty much unspecified still(outside of 
dmd,) I believe(don't quote me) that walter said it's supposed to 
be part of the spec but I could never find anything.

there's a few bugs filed on it
https://issues.dlang.org/show_bug.cgi?id=10372
https://issues.dlang.org/show_bug.cgi?id=11287
https://issues.dlang.org/show_bug.cgi?id=10371

probably others
