faster): not going through function pointers by default there are no jumps in the function preamble (padding) slowdown depends a lot on the type/scale of software - x2 to x5... Live++ 51 HCR performance

plain pointer, as Nim objects have no overhead as long as we do not use inheritance and when no padding to word size is needed for tiny fields like int8.) Capacity and length are stored also in the memory a bool and an int64, in one direction 7 bytes have to be ignored, and in the other direction, padding is necessary for the 7 missing bytes. We perform a cast by writing the desired type in square brackets
