The dataStack functions tend to get over-used in muck muf and traditional forth due to the lack of dynamic variables, with consequent losses to code readability.
When using these, please be sure your code could not be better expressed using local variables (which are just as fast, and usually more readable).
When using stack and stream objects, note that generic object
functions are also applicable: For example, vals[ may
be used to extract the contents of a stack object in a block.
