True, but this never worked for the pre-stacked method either.

Off the cuff, I propose that we make a special object that is
a thread that calculates the value by running the function, and
wrap that expression thread into a VPI expression object. Thus,
there is no stack extension, in fact the existing instruction
set is used to evaluate the function on demand.
