I think it's because it's using rdmd, and that runs dmd once to generate dependencies, and one more time to compile.

It's not specific to static foreach or the new compiler:

I bet you are using `rdmd`?
It runs dmd twice on your main file ;-)

I'm just clicking on the run button on the web page you linked to. How do I not run rdmd there?

Oh because I thought run.dlang.io wasn't using `rdmd`.
However, there was a minor glitch today when I added support for flags and stdin to the docker images [2]. The good news is that it has been fixed [2] & everything should behave as usual.
Sorry for the inconvenience and continued happy hacking!

Now:
Compilation or running program took longer than 25 seconds. Aborted!

Hmm, seems to be a temporary error. It works fine for me. Are you still experiencing this?

Just tried again, now working (and displaying only one list of numbers) thanks.

I cant find the matching dlang.org pull request. The one that specifies the changes applied to the grammar.

Maybe good subject for an AMA (though not many upvoted so far). It's pretty cool that it was added on an afternoon during the hackathon.

 https://www.reddit.com/r/programming/comments/6pn257/static_foreach_added_to_d_compiler_nightly/

Could someone post to Hacker News - I don't have enough rep there for stories to propagate.

Can always post another story later on explaining the practical benefits of static foreach (good topic for a D blog post) - marketing is about repetition.
