> As an analogy, this whole discussion of PLs in CS circles is like complaining about whether we should use `dot` notation or `d/d(t)` notation or whether we should use `t` or `x` in solving a differential equation Until you start manipulating the 'dt's on their own which wouldn't occur to you if you were using the dot notation. (And then some people tell you that it's illegal, or maybe okay but only if you've taken real analysis... it gets confusing)
