> Readable and compact, not bloated :P

Inlining makes bloat - but is usually more performant.
Loop-unrolling of small loops makes bloat - but is usually
more performant.

> Optimize in iterations :P

Hand-written asm is usually slower because there are only a small
number of asm-writers that know all the optimizaztion-tricks that
compilers have learned for decades. F.e. the code of clang 12 is
meanwhile somewhat faster than that of gcc 11. I think in five
years absoutely no asm writer can beat a compiler.
