When I had to learn golang, picking up the syntax was easy, but it has many gotchas that you end up having to spend time to learn them anyway, which don't exist in Java (e.g. the Java compiler requires final or effectively final vars to be passed into lambdas, golang happily complies ending up with race conditions). I don't see why learning language features is an issue. The language offers features to provide more correct and more expressive code. golang does not solve the variable vs reference issue at all by the way, and in fact, introduces weird edge cases, such as nil interface not being equal to nil. Why do you say Strings not easy to understand?
