This is not a problem with vector computations, but the particular implementation. The vector expression in your example is by far the most readable. It is literally the math you had in mind. De-vectorization in code is like embedding ASM code: you had to write it out because the compiler sucks. Good language design should favor lucid and concise syntax, and good compiler implementation should make it not necessary to circumvent it for performance. In this case, the compiler should be implementing those vector expressions without allocating unnecessary memory.
