In a Forth optimizing compiler, stack words (in almost all cases for
"sane" 
code) do not generate any code. Such words do not do any useful "work,"
they 
just reorder the stack for words that do, and instruction/address mode
selection 
will take care of it. 

The algorithm might be useful for a hardware stack engine (although I
would 
hope that such chips don't do e.g. "SWAP +" as two separate operations).
