> That's great! Let the compiler figure out the optimal data layout then! GHC, which is without a doubt the smartest compiler you can get your grubby mitts on, is still an extremely stupid git that can't be trusted to do basic optimizations. Which is exactly why it exposes so many special intrinsic functions. The "sufficiently smart compiler" myth was thoroughly discounted over 20 years ago.
