As for the other two links Go fanboys like to throw them around to feel happy that they beloved language is comparable to programming languages developed in the 70's.
Ignoring and being selective are different things. The golang designers have made intentional choices and the reasoning is provided in the links I sent. I am not a fanboy. IMHO, Go would have been MUCH more interesting if goroutines did not run in a shared address space and if they implemented generics (even as a hygenic macro..)
The things that you left off your list that I think are much more interesting are:
- Weak/Strong purity, enforced by the type system
- uniqueness typing
- chan is too special. The difficulty with implementing a good netchan interface is starting to show this.
