| // This file introduces a simple but powerful generic dynamic array concept. | |

| // with these structs. | |
| // | |
| // This approach was chosen because: | |
| // 1) Type safety: Array of int should be distinct type from Array of char. | |
| // Not only does it require more state management it is also a mjor pain to work with because we always | |
| // need to cast to our desired type (or pass the type to some acessor macro). | |
| // This discvalified the one Array struct for all types holding the size of the type currently used. | |
