Curious. I read GP as "I really want to be able to tell compilers to make these changes", but with exception of your SoA example, all (5) responses assumed it was a desire for a sufficiently magical black-box optimizer. Which in retrospect seems plausible, but first seemed to me quite odd. Of course you want to be able to slap in a paragraph of Halide, or annotate with memory organization... <puzzled expression>. Too much time thinking metaprogramming open compilers and inline multilingualism.
