But with respect, I still think I disagree with your conclusion. Every problem has usage patterns that cannot be expressed to custom STL allocators, but can be easily leveraged in a custom container, such as a fixed-block allocator implemented with a flat array. And applying a fixed transformation over an array of homogeneous types will very likely result in much better cache coherency than iterating over a vector of polymorphic types and invoking virtual methods. | |

The array-of-structs vs struct-of-arrays is very dependant on what you're trying to do - there is no hard and fast rule about which one is better. | |
