>Actually, your sample "solution" is (was?) also a much used pattern in Julia - especially before we had such a powerful broadcast implementation. To add some more historical facts to this: before broadcast, we mostly used maps & zips in Julia. Which is not very elegant if you want to write down your math. Even with broadcast, some math nuts still complain that it isn't close enough to the actual math :D So consider, that those people are Julia's user base ;) And then, someone pretty much implemented broadcast in their freetime and added it as a PR to the Julia language. This is how the language grows, and a large part of that is possible, because it takes relatively little time to come up with a performant implementation of such a difficult problem. And now we have broadcasting in the language, and maps + zips are indeed less idiomatic... Because anyone who started using the new broadcast immediately thought it was an improvement to "the old ways".
