Just to be clear (otherwise someone is going to link to this thread and say that Julia insists that you should write long, devectorized code): while writing slightly longer, more explicit code is – for now – sometimes the easiest way to make your code really fast, this is not a Julia mantra nor a philosophical underpinning of the language. We would like, through improved compiler technology, to make the shortest, most convenient way to write something also the fastest. But we won't cheat to accomplish this by doing something hacky that doesn't generalize – and that *is* a philosophical underpinning of the language.
