And Erlang has already run many telecom infrastructures for decades. Surprising given how fragile the multi-host implementation has proven.
Erlang/Elixir are neat languages, and right next to Julia for fun. =3
Haven't personally deployed this version yet. ymmv =3
And I'm saying that as a complete fan of Erlang, it is one of the few pieces of software 'done right' that I'm aware of. Unfortunately that comes at the price of being unsuitable for highly optimized number crunching unless you want to break out the C-compiler and write an extension.
Python is similar, but there the extensions have been grafted on so well lots of people forget that they are not part of the language itself. In the Erlang world you'd have a lot of leaks and conversions to make something like that work and it would likely never be as transparent as python, which in many ways is both the new BASIC and the new FORTRAN.
