		pcwalton on Sept 24, 2017 \| parent \| context \| favorite \| on: Why undefined behavior may call a never-called fun... Because type safety makes a lot of optimizations sound. C and C++ have to use undefined behavior rules to achieve a lot of optimizations that type safe languages can more easily perform. In fact, the optimization that the article is complaining about is really only a problem because C is not type safe.

So that's my point. If C was those few percentage points slower, and died, then we'd have better languages sooner.
