Not for you. But I know quite a bit about the guts of the BEAM VM and I think this is a very interesting development and if the jump is large enough it may well obviate the need for a whole slew of situations where you now have to fall back to externally loaded functions in different languages, and that would make a bunch of stuff far more elegant. Yes, those externally loaded functions will (always) have a speed advantage, but if the advantage drops below the level of the cost of adding an external module then that would be pretty good news.
