Hello, http://www.erlang.org/eeps/eep-0031.html#reference-implementation states that it will be implemented in R13B04, but I can't find it in my distribution (ubuntu packages from ppa https://edge.launchpad.net/~erlang-dev/+archive/ppa ) Is it implemented in R13B04 or how else can I find the implementation? Best regards, Anton Lebedevich.
