@screwtape @vavakado @kar I don't remember saying such, I wouldn't know if CDADR gets one instruction, but I probably would say 1. CDR coding is nice if you're tight on memory*, which people were at the time and 2. the funky hardware was faster until compiler tech caught up

Smalltalk on a RISC is cooler hardware in my worthless opinion (take *that*, AMS), the details are only in papers but I think there's enough for someone to implement it; someone doing hardware now should think about what compilers/software can't help with, and put that in hardware

*cache should count for this too, but no one CDR codes now, oh well
