Hello, it works fine here. Maybe there was another error that you
removed when you have minimized the example. See
https://run.dlang.io/is/ZrW7kI, that says that the example works
since 2.068.2. Although that are are possibility that it was
broken before a patch release, since only latest path of a minor
release is tested on the site, in which case updating the
compiler would fix the issue.
