## Parable: rso It's sometimes useful to be able to reverse the contents of the stack. Parable now provides for this via **rso**. 1 2 3 At this point 3 is on the top of the stack. If we want to discard the 1, we could do something like: [ nip ] dip Or, now: rso drop rso This becomes more useful when the stack is deeper. Perhaps it'd also be nice to have something like this to do the above (where invoke<rso> reverses the stack before and after execution of the pointer): &drop invoke I'll have to consider this a bit more.
