You'd be more helpful if you specified what else would you deem appropriate -- as opposed to resorting to snarky sarcasm that brings nothing interesting to the discussion except supposedly degrade people whose tech choices you disagree with.

The phrase 'undefined behavior' only makes sense in the context of an ISO standard.

For any particular combination of compiler, OS and computer architecture there are no 'undefined behaviors'; you only care about the concept if you want portability to a different compiler/OS/architecture.

So the idea that C++ sucks because of 'undefined behavior', so let's use some random language without an ISO standard or any portability guarantees at all is completely and utterly insane.
