It appears like all failures are due to vibe.d. Since the only reason why it overrides state() is to expose it as @safe, and it's very unlikely that anyone else did the same, I'd propose to just keep Druntime as it is in this case, but I would add a proper static-if within vibe.d.

Not a huge fan of adapting packages to upstream breakages, b/c it requires
every vibe.d user to update their dependencies.
But there doesn't seem to be a simple solution to this.
Can we do that in a vibe-d point release (i.e. 0.7.31)?

Still there seems to be a bug in the override checking of dmd, I think those should have never compiled since we don't allow overloads based on attributes.

dmd -c -o- bug

The workaround is in the 0.7.31-beta.2 release. I agree in general for such workarounds, but from a pragmatical point of view, the cost/benefit ratio seems to be quite favorable in this case. And most of the time it's necessary to make some changes for a new DMD release anyway, for example due to improved diagnostics.

FYI as far as I can tell DUB is still affected by this:

https://ci.dawg.eu/job/projects/1324/REPO=dlang%2Fdub/console

So what's the best way we can deal with this?
I guess there's no way around releasing a new DUB version with the updated
vibe.d dependency?
