I think https://issues.dlang.org/show_bug.cgi?id=18047 is also
fixed in 2.078.
It was fixed in https://github.com/dlang/phobos/pull/5911, but it
is not shown in the changelog.
https://issues.dlang.org/show_bug.cgi?id=17459 was also fixed in
the same PR and
it is shown in the changelog.
Could you investigate this please?
