redoing SCM representation in 2.2

Hello list, I'm looking at new SCM representation and tagging possibilities in 2.2. Read the whole mail please, as it's a little complicated. The current system has a couple of problems: 1) You can only tell a pair by dereferencing the pointer and checking the cell's low bits, and then we

scheme problem!

Somewhere in the program I have, (pk x) (pk (caar l)) (pk (equal? x (caar l))) It outputs ;;; (number) ;;; (number) ;;; (#f) #f is there more to this then meets the eye? /Stefan

So we'll see a 48-bits solution in 2.2? Sorry I can't say I'm clear since it's a long article. -- GNU Powered it GPL Protected it GOD Blessed it HFG - NalaGinrut --hacker key-- v4sw7CUSMhw6ln6pr8OSFck4ma9u8MLSOFw3WDXGm7g/l8Li6e7t4TNGSb8AGORTDLMen6g6RASZOGCHPa28s1MIr4p-x hackerkey.com ---end k

Re: redoing SCM representation in 2.2

Looks interesting. I would like to reserve an object for the stack machine I use. Actually I will be fine to model the prolog engine ontop of your segestion if it was not for one idea. So you have a layout of this (X Tag14 Data Tag8) Consider a the following tag in Tag14, frame-tag. Then Data is

Re: scheme problem!

Oh well, I found the issue. It was because of my special system. The printed representation of unify variables that point to a point to a point to a symbol got printed as a symbol. I really need to tweak the output to hint if it is a unify variable. And if wingo managed to squeeze in tagging - so
