Go is web-oriented, so it seems, and I'm sure it will be marketed as the "one size fits all" solution for web development, multi-core and whatnot. But D goes deeper. D raises fundamental questions about how a good program should look like, what is good / practicable. I know that this approach doesn't sell, but it's the best I've ever come across. D makes you think and re-assess your own code time and again.
I basically I agree with this. But lately, I was asking myself, though, whether me classifying Go as simplistic was wrong. I programmed the canonical Scala trait sample in Go. In that sample from the Scala book there is a trait Rectangular with a upperLeft and bottomRight point. Some class Rectangle extends trait Rectangular. I could get the same accomplished using delegation in Go. The solution in Go is much much simpler and from what I can tell the power is the same. So this made me think.
I guess the solution in Scala is easier to recognize for the reader as the code is more structured using specific language constructs. Therefore someone reading the code would easier see the structure in the code and understand the solution. Nevertheless, with a simple construct like delegation with some compromises in visibility you get almost the same power as with inheritance, traits/mixins, etc. This is still amazing to me.
