To phrase succinctly the (direct) counter to the previous blog post: Julia makes possible the kind of combinatorial composition (and therefore, radical modularity & reuse) that is simply not possible in most languages. This will lead to some friction as the community figures out the right design patterns in these uncharted waters, but on the flip side one already gets many superpowers, provided one is careful about testing the composition works as expected, rather than just blindly assuming it does.
