It fills the same niche that D is trying to fill:

- Systems programming language with ideas taken from dynamic languages like Python to make life easier
- Fast compile times
- Built-in support for concurrency

Some of the people in the Go team include Ken Thompson and Rob Pike.

As a matter of interest these people have been mentioned in a few past D NG articles. Apparently Ken Thompson designed UTF-8.

Sorry if I'm stating something you already know, but Ken Thompson also was one of the main creators of UNIX.

I watched the video. The language sounds like a cross between Smalltalk and C, but with better concurrency support. I was somewhat underwhelmed, but I do think the concurrency features are interesting.

I watched part of the video, though I'm curious enough about it that I'll probably watch the rest later, esp. if Go keeps coming up around here.  However, for me personally "normal" static typing is too rigid for just about anything.  I would never choose a language that didn't either have duck typing or good templates that basically amount to compile-time duck typing.  I'm not sure how Go addresses this.

Thanks.  I had forgotten that.  Whenever a new language comes on the horizon, it's useful to know exactly who are the people behind it.

I tried watching the YT video but, as unfortunately my Three mobile broadband is just so s l o w, I stopped after 10 mins. (Anybody thinking of Three in your neck of the woods for broadband forget it.)

Anyway I think the speaker (Rob Pike) said something along the lines that "no new systems
programming language has been developed in the last ten years" and there was no mention
of D (at least that I picked up).  Wonder if they ever looked at D or if Walter knows any of
these people apart from just name?

You could take like the first 15 minutes and just replace the word 'Go' with D.

I found the way interfaces were handled to be quit interesting, similar to how Andrei is doing his range implementation. Not sure if an object hierarchy would get in the way of having it in D though.

For those who didn't/can't watch: A function requires a specific interface; the compiler checks that the functions are implemented at compile-time.

See http://golang.org/doc/go_lang_faq.html#inheritance

"Rather than requiring the programmer to declare ahead of time that two types are related, in Go a type automatically satisfies any interface that specifies a subset of its methods. Besides reducing the bookkeeping, this approach has real advantages. Types can satisfy many interfaces at once, without the complexities of traditional multiple inheritance."

That, my friend, is duck typing.

Incidentally, with pure duck typing I tend to feel a little bit...naked, unconstrained.  So while it's very flexible and allows any compatible types to "just work," it also makes it a little hard to define any useful constraints in practice.  Smalltalk makes this a tiny bit better because of its message passing syntax (the keyword arguments make things a little more clear), but I think D strikes a nice balance with templates and metaprogramming techniques, while still having some type-constrained relationships where they make sense.
