The team working on Go regularly rejects proposals that make the language more complex just to save a few keystrokes. They and most experienced Go programmers value the simplicity of the language. Syntactic sugar is routinely rejected out of hand. The increment operator (++) isn't even allowed as an expression because it is too easy to make confusing and error prone code. (you can still use it as a statement, you just can't do like foo[a++]). I wouldn't be worried about the language increasing in complexity much. :)
