If the functions need to do that sequentially, there's no problem --
you pass the reference to the first function, then the second
function. If they need to operate in parallel you have to make a copy.

Obviously you've read your Henry Baker,
http://home.pipeline.com/~hbaker1/ForthStack.html (I cite this for the
benefit of others interested). He explains how linear logic works and
why it insists on only one reference per object.
