Undefined/implementation-defined behavior are necessary if you want optimal performance (unless the compiler requires formal proofs of correctness). >it is human nature to forget High-performance programming is a job the average human does not do. A professional programmer should use spaced-repetition technology to rise above human nature, and use tools like valgrind for extra safety.
