compiling to python byte codes

[Maurice LING]

Probably my question should be phrased as, given what x86/PPC processors 
are register-based (even after more than a decade from the publication 
of the book "Stack Machines - the new wave") and there isn't much 
examples of stack-based processors, why is there a difference? It seems 
wierd to me that if stack-based machines (physical processors or VMs) 
are so good, why hadn't the processor engineering caught up?

You've totally missed my question but thanks anyway, I've learnt. My 
actual question had been partially answered.

Thanks
