Thanks for building such a interesting project.
Btw, not complaining. Just wanted to let make you aware of maybe another possible bug.
You can also check the examples in the fetched folder.
e.g.
cd /root/.dub/packages/vibe-d-0.7.21-rc.3/examples/download/
dub run
When I did the dub run I got this:
c:\Users\kheaser\AppData\Roaming\dub\packages\vibe-d-0.7.21-rc.3\examples\download>dub run
The following changes will be performed:
