I can think about the opposite too: to remove the built-in dynamic arrays and replace them as it's being done with associative arrays, keeping only the syntax sugar and mapping them to the Array/Vector. Is this a bad idea? (this is only about dynamic arrays, at the moment built-in fixed-sized arrays have to be kept).
