> Similar performance characteristics (or better) than Go. Nope. It's without a doubt 100% better. The GC is brilliant and realtime with deterministic properties. The community has outperformed C++ in ray tracers and games, Ada in text manipulation, etc. It's absolutely freaking blazing since it compiles to really tight C and takes advantage of the 50 years of C compiler research & design.

> Library situation is a little iffy. Libraries are hardly iffy. Any C code be called, and most c++ code can be called very, very easily and with little boilerplate. The standard library has a huge pure section, and for almost everything else it has dozens of bindings to C libs. And there are plenty of existing libraries in the babel library manager, such as SFML.

You're overselling it. While you can call C code, the interface is often not very Nimrod-y and it's not automatic, you have to declare prototypes, and there are absolutely holes in the stdlib - the lack of any arbitrary precision/bignums library for instance.
