I'm trying to run unittests using `dub test`, and I wanted to

But I tried adding this to my dub.sdl file:

But now I get linker errors:

different error message though.
Yeah, that's probably it. Hm... this feature isn't very usable
if I can't use it with dub. And the bug report you linked to
also has an example that fails with straight dmd (even without
unittests).

Yeah, it's currently not usable, because DMD thinks the template
is already instantiated in Phobos / druntime. I tried to work
around it in my projects and it didn't work out.
I want to enable it by default but there's 2 issues blocking it
ATM (see https://github.com/dlang/dmd/pull/11925). Once that PR
is green, we can enable it when compiling druntime / Phobos and
your linker errors will disappear.
Also, dub-wise, you can't really use `-preview` before the latest
release. That's why we added
