Hi all,

there is something interesting in Forth: it does optimizations in a very specific way. That is knowing how it works. The better algorithm is the better optimization.

But that has drawbacks. Nobody knows every system. And no system knows every intention.

There is one big part that could be optimized in a simple way - it is >R and R> and all words that are similar.

">R" (especially in ANS terms) means to bring something to a second "stack". "R>" to bring it back. This could be virtually something like a register at the machine you have.

Why not implement this more elaborate about what ">R" means? I know CS-ROLL etc. - it should not be this weird.
How about defining ">R" has nothing to do with return stack but it could affect it? Why not saying to programmers to use it, as long as it is stable inside one definition of a word?
It would be "semi-compatible" with ANS.
All the return stack tricks you had with old implementation are no longer recommended today.

Here I remember Reva that had a word to bring something into a machine register. Maybe it was ">a" or such. But this was nothing like a stack at all.

For implementation reasons the return stack should not be made available to the programmer. It should be accessible for the system implementor only. At least in "official terms" of a specification.

How do you think?
-Helmar
