One could make an argument that with PHP, copy-paste deployment is popular. Of course, it's not quite the same thing, as you'll need Apache/etc. setup, however that is one of PHP's strengths. It's good to see another language doing something similar, but in a nicer, far more performant way: specifically for web development, the way Go does stuff is brilliant in my opinion.

Ah, I was not clear. I mean copy/paste without the need of a runtime. With Delphi (go?) you just ship the exe (and can even put inside it the resources).

Having a kind of packaging for shipping is more or less popular now...

In theory it's also true of ASP.NET. You have a magic folder of CLR-compiled binaries you drop into the IIS site root folder and it "just works" (or doesn't, as the case may be).

It's quite common in the Java world to build a 'fat jar' which is the same idea, all dependencies other than the JVM itself in a single file.

It is pretty common on Windows and Mac OS X worlds, but it seems not so in GNU/Linux.
