Erlang pattern matching is awesome. Matching on binaries makes it very easy to parse protocols.

Re concurrency. I learned Erlang before Akka. It took me a bit but I find Akka more ergonomic. Akka will easily handle millions of actors on a single machine, too. But I always miss matching on binaries.

Another good one is protoactor for golang. That will also do a million actors no problem. Comes really close to Erlang in terms of how concise the syntax is. But again, no binary matching.
