I've been playing around with go quite a bit lately, and now think that being bundled is actually a really serious advantage.

Being able to just to "go fmt", without needing any additional tools, is a really great thing about the language.

The only danger that I can see (and it is a big one) is that Python doesn't have the same kind of consistency that go does. It might end up failing just because so many people use Python in such different ways.

Yes, one advantage is that tools/editors will start to standardize on it. I quite enjoyed the seamless experience of go formatting as I started learning go. It felt like one less thing to worry about. Just worked.
