BTW, I don't think that's the right way to implement Pascal's stack
structure. Instead, I advocate using hygienic renaming of internal
procedures and the variables in them, and rewriting the internal
procedure calls to pass the arguments of the outer procedures as well.
It costs you a little bit extra in stack space, but not usually as
much as you spend keeping track of a hierarchical stack structure, and
it allows you implement Pascal's stacks with a single contiguous stack
space.
