> My personal dream endgame would be a dynamic language, such as Python or Ruby, that includes the concurrency features such as goroutines and channels. Directly as language features. AFAIK, the existing GIL in the reference Python and Ruby interpreters makes adding true goroutines impossible.

Have you had a look at Erlang and Elixir? The former is not as dynamic as Ruby (not much is), but it's a nice environment, and another step up from Go in terms of all the facilities for fault tolerant and distributed programming.

I second this recommendation: I've started a project with Elixir two weeks ago, and so far I really love it. As far as syntax goes nothing beats the elegance of Python, but in terms of overall application architecture OTP [1] is just miles ahead.

That said I can definitely imagine picking up Elixir for a purely imperative/OOP programmer being quite an undertaking. But definitely worth it.

I would like to mention LFE. Lisp Flavored Erlang (http://lfe.io/) is a great addition to the Erlang/Elixir world/ecosystem. Go on, test it out!

I work as an Erlang dev. It is really awesome. It has a simple and consistent syntax (even if don't like the comma, semicolon and period terminators), the most powerful native concurrency semantics I know, the best error detection and handling semantics, pattern matching (you make the compiler work for you), an awesome virtual machine that took correct design choices (gc per process, iolists for concatenating strings), incredible tracing support, good support for connecting with other programming languages, a good optional type system (Dialyzer, http://learnyousomeerlang.com/dialyzer) for detecting type errors and good patterns as supervisor, gen_server and gen_event . It also has a vibrant community that has created good libraries like Proper (QuickCheck-inspired property-based testing tool for Erlang) and Cowboy (simple http server).

I have worked with C, C++, Java, Ruby, Python and Javascript/NodeJs. I really like Python and Ruby as general programming language and for creating prototypes, but I would definitely use Erlang for any real backend project.
