Julia is awesome, but..
Here's a language that gives near-C performance that feels like Python or Ruby with optional type annotations (that you can feed to one of two static analysis tools ) that has good support for macros plus decent-ish support for FP, plus a lot more. What's not to like? I'm mostly not going to talk about how great Julia…

Interface Upgrades in Go
Much has been written about Go’s interfaces . They’re one of the language features I like best, providing a very pragmatic trade-off between the complexity of more powerful type systems and the anarchy of duck typing. If you’re not already familiar with Go or Go’s interfaces, I’d encourage you to read an introduction…

Go 1.3 Linker Improvements
Go obtains much of its compilation speed from the Plan 9 compiler, of which it is a direct descendant. The Plan 9 toolchain deferred much of the work traditionally performed by a compiler to the linking stage and its performance was summarised in section 8 of this paper
