If the standard requires that the control-flow stack behave as a distinct
stack, is not allowed to have control-flow interleaved with user data on
the data stack, and can not use the return stack because it would break
threading, just how would you implement an ITC Forth when neither of the
two available stacks could be used temporarily as a control-flow stack?
Are you suggesting using a dedicated third stack?  ...
