Google just released a new open source programming language called Go. Go is intended to offer built-in support for concurrent processes, make the most of modern hardware and deliver a super-fast coding experience. Google says in its announcement that "Go attempts to combine the development speed of working in a dynamic language like Python with the performance and safety of a compiled language like C or C++." Go was created by a five person team that includes UNIX co-creators Ken Thompson and Rob Pike.
It's not for everyone, but we talked to a variety of developers who are looking forward to kicking the tires. Below are opinions before launch from three developers we have a lot of respect for. Two are enthusiastic and one is skeptical.
Rob Pike also gave an hour-long talk about Go late last month.

I'm definitely on the lookout for C-like languages with good C integration and solid package support (for organization). Hopefully Go provides the former with its "syscall" package (or something similar) - building on existing libraries is a huge boon to young languages, as Scala and Clojure have shown with their Java integration.Organizing big C projects is always a challenge, and borrowing packaging ideas from higher level languages like Python could really help.
Can't wait to see the site and play with a few examples.

Go appears to be procedural language, based on C/C++ syntax, skewed heavily towards C. It has C memory manipulation model with addresses and pointers, which is complicated and not used in Java, PHP, Ruby, etc.There is nothing in this tutorial that attracts my eye, other than built-in parallel processing capability. C historically lacked threading (although current versions have it), but having it built in natively into the language is always great.
I am a fan of Java and Object-Orientation, so new procedural languages sound like a thing of the past to me.
If this is positioned as alternative to JavaScript, I do not see why this is necessary. Why not take JavaScript and make it better / add richer libraries like JQuery as part of the language. What Google has done with Gears for example, is built stuff using native C/C++ code and wrapped it into JavaScript calls - I think that is a better way to move forward and to make things faster.

This is a very clean and powerful language. It's a direct descendant of C with elements of Haskell, OCaml, python and erlang visible as influences. It seems like yet another attempt to make a "better C than C", and from a first shallow glance it seems like a clear winner.Objective-C fans (mac programmers) will probably sniff that it's nothing new, and that clean message passing semantics have been available to programmers for decades, but there are some deep differences; Go is not an object oriented language although you can use it in an objected oriented manner. In many respeccts Go is not a new language, it will seem very familiar to anyone who has used C or C descended languages; and most of the advanced features that it adds to C are implemented in other languages.
Go strikes a good balance between legibility, low-level functionality and high-level functional programming features. It will have a strong appeal to programmers who are interested in the type safety and concurrency friendly features of Haskell or erlang, but want to access them in a more familiar C-like syntax.
It has a good chance to make type-safe concurrent programming a mainstream choice.
