No. We've been able to return by ref for ages. However, when std.datetime was
originally written back in 2010, there were bugs that prevented it from
working for a number of the functions in std.datetime. Unfortunately, I can't
remember what the bugs were at this point, but they've long since been fixed,
and I just finally got around to making it so that those functions in
std.datetime return by ref instead of void.
