I did not bookmark it, but there was this fun blog post about writing a number crunching HW assignment in Scheme (much against contemporary wisdom). But It ended up other implementations in C. The trick was to write it in CPS and keep hand transforming it iteratively till it was efficient assembly in a different syntax. I would still argue that that you are really writing in a high level language/abstraction and the rest is mostly tedious transliteration with special attention to keep the FPUs busy, efficient memory loading and register allocation.
