hayley: We don't need no stinking revival! Medley uses CDR-coding because it has a fixed limit on usable memory (and even that is much bigger than the largest possible D-machine)

CDR-coding was for when RAM was expensive

i don't know why sybalsky increased the VMem size from 64m to 256m and kept cdr-coding
17:12:21

Too hard to rip it out, maybe?
17:12:45
masinter
no, you could just have done (DATATYPE CONS (CAR POINTER) (CDR POINTER))
17:13:20
masinter
or maybe LISTP instead of CONS

And then you have to rebuild the image from scratch, which until recently we couldn't do, no?
17:14:13
masinter
THey knew how to build new images, it's just things changed and we didn't really start with a clean delivery of a working system

question: is mutating &rest arglist portable?
22:51:52
hayley
From memory it interacts poorly with APPLY.
22:54:05
hayley
Somewhere, but I forgot where.

"The value of a rest parameter is permitted, but not required, to share structure with the last argument to apply."

With regards to masinter saying "CDR-coding was for when RAM was expensive", cache misses are also expensive.
