Any chance this could get fixed? I was seriously relying on this feature working; it was mentioned the introductory book as working, and the online docs don't indicate a difficultly, so I incorrectly thought async was working.

This should be fixed/implemented for the new vibe-core package, which
is not yet the default in 0.8.0. Try adding this to the package recipe
to force using vibe-core: 

dependency "vibe-d:core" version="~>0.8.0-beta"
subConfiguration "vibe-d:core" "vibe-core"

I tried this, paranoiacally ran dub upgrade and dub --force and got the same error.

Apologies, not so, I didn't have the configuration exactly right. Now it doesn't do that. It runs and does not terminate with an error, just hangs. After 10 seconds I hit ^C. When I attempted to rerun via dub it could not listen on the same port. Here's the output.

I'll try running it again.
