Have you programmed in Google's GO programming language by Google today?

Their Hello World is weeaboo!! It must be good!

Go has fast builds, clean syntax, garbage collection, methods for any type, and run-time reflection
Sure doesn't seem like a systems language to me - honestly, it seems like a replacement to the shit-show that is Java. It couldn't have gotten here soon enough. Not sure why they're calling it a systems language actually.

Some of it seems extremely attractive, in particular slices; that looks like a truly great language feature. Built-in concurrency looks really good; no other language has done this properly, and most new ones don't even try (I'm looking at you, Python). Another thing that in my opinion is good:

Go does not support function overloading and does not support user defined operators.
It's like D done right. It's like managed C with built in GC/threading libs and all the old legacy and error prone shit cleaned out (built-in arrays, no header files, no automatic type conversions, case labels don't fall through automatically, etc).

Some really nice improvements over C++; for instance C-style method declarations only (no duplicate syntax), open classes!!!, new() is a function, automatic interfaces (static duck typing! roxors!).

Here's one thing that doesn't look good:

When a package defines an object (type, constant, variable, function) with a name starting with an upper case letter, that object is visible to any other file which imports that package.
Having the language interpret naming conventions for things is a bad idea. It was a shitty idea in Python and it's still a shitty idea.
