 Finally, the maximum efficiency is typically achieved when the output array of a vectorized operation

 fused with any nested "dot" calls. For example, `X .= sin.(Y)` is equivalent to `broadcast!(sin, X, Y)`,
 overwriting `X` with `sin.(Y)` in-place. If the left-hand side is an array-indexing expression,
