I'd say expansion on that functionality would be more widely useful than just about anything else I can think of with regards to optimization (because it's so easy to use, and yet so powerful.) Maybe start with making it fully use AVX instructions for the operations? IIRC, currently, even if you use the AVX or AVX2 compiler flags, it will always generate stuff like this: vmovups (%rdx),%xmm0 addps (%r8),%xmm0 vmovups %xmm0,(%rax) rather than using vaddps. >From there you could make it support arrays larger than 4 elements, e.t.c....
