I heard that proving that two pointers do not alias is a big 
problem in compiler backends and that some or most auto 
vectorization optimizations do not fire because compiler can't 
prove no aliasing.

A new language used in Unity game engine is designed such that 
references do not alias by default for optimization reasons. I 
haven't looked into this topic further but I believe its worth 
checking it out. Data science people would benefit greatly from 
autovectoriztion
