I agree strongly with this, it seems like the author has some expectations from his known language pool. Reason #3 about lexical scoping is the big one to me, as you can (and might want to) arbitrarily block variable scopes in many languages. The other components seem to be mostly that Go is still in flux as a language so things that are silly today may be fixed tomorrow, but that's kind of a built in expectation with the ability to transform source files to current. This feels like a lot of the early Java issues that were resolved some time later.
