that is getting near-native performance on browser environment.
What this means is that in near future (few or more years) it is
completely feasible to have Ruby interpreter running in near-native
performance on supported browsers. And with poorer performance on other
languages like Coffeescript. And then there are projects like opal that
already bring ruby to the browser. (http://opalrb.org/)
So what do you think, what will this mean to Rubyists in the long run?
