And thanks to dmd-nightly, also on run.dlang.io:

Oh - seems like that was due to a different behavior between FF 
and Chrome :/
(Chrome unescapes the semi-colon by default). This has been fixed 
now, so the link above or this shortlink should work:

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 ;-)

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!

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)

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.
