Stream Processing for Go
Wow, Pony! Pony is one of my favorite young languages. It fits a similar niche that Go fits (not saying that either language can't be used for other purposes), in that they both are great for building cli tools with good concurrency primitives.Pony, however, uses the Actor model like Erlang (although the programming model is a bit different). In my opinion this is a superior model for concurrency than goroutines. I highly recommend checking it out if you have any interest in cli tools or erlang/elixir.
