I think Crystal could fit this bill, yes: it has Ruby syntax and the concurrency model will be something like Go (spawn and channels, but we are still working on this). And the code ends up without much repetition, as you have generics, macros, very few type annotations, and things like sort, map, select, inject, etc.
The community likes to call a library as "shard", so I think we'll eventually end up using that name :-)
For now that just lists GitHub repositories. Right now there's a very basic package manager that fetches repositories from GitHub, but it's too basic. Someone is working on a much better package manager ( https://github.com/ysbaddaden/shards ) that we'll probably incorporate in the future.

You can see a list of shards here: http://crystalshards.herokuapp.com/
