I love how much thought and polish went into this, just like so many other Erlang features in recent years: counters, persistent_term, thread progress, ETS scaling, process groups... There's been talks of JIT for quite a few years, but they didn't want to merge it in until they had something that's easy to maintain, and doesn't introduce significant performance regressions. The end result looks really solid.
