I just submitted https://issues.dlang.org/show_bug.cgi?id=15328
which is currently blocking my work on containers.
In brief the postblit isn't called upon calling
Range save() { return this; }
which of course is less than helpful.
Reductions of the example would be awesome - I reduced it a
fair amount compared to the initial code, but I'm sure someone
without that context could do a much better job.
Thanks,

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=11287
