A recent talk about Go, Google I/O 2010 - Go Programming, the real talk stops at about 33 minutes: http://www.youtube.com/user/GoogleDevelopers#p/u/9/jgVhBThJdXc
At 9.30 you can see the switch used on a type type :-) You can see a similar example here: http://golang.org/src/pkg/exp/datafmt/datafmt.go Look for the line switch t := fexpr.(type) { Originally Go was looking almost like a toy language, I thought Google was thinking of it as a toy, but I now think Google is getting more serious about it, and I can see Go has developed some serious features to solve/do the basic things. So maybe Andrei was wrong, you can design a good flexible language that doesn't need templates. Compared to Go D2 is way more complex. I don't know if people today want to learn a language as complex as D2. Go target flexibility and performance is not C++-class one (but probably it's not too much difficult to build a compiler able to produce very efficient Go programs). In the talk they show some interfaces and more things done with free functions, I don't know those things get compiled in assembly. Bye, bearophile
