> specially when you take in consideration all the undefined and unspecified cases in C and C++. That is an odd way of putting it. Aren't undefined/unspecified behaviors allowed to be implemented in whatever is simplest for the compiler if it prefers? Sure many modern compilers leverage them to expand the power of their optimization engines, but that isn't really a language difficulty case.
