Wow, didn't know there is an article about this. Looks like we all think
about same things. Personally I was too lazy to propose in this NG
similar but less advanced idea. So my small (but valuable, IMHO) addition:
Add explicit vectorisation for some common predicates (`a == b` e.g.)
for sequential memory blocks (arrays) and ranges with elements of such
blocks (called "segmented" in the article).
