Stack Object

Stack objects are used internally by the interpreter. They are used to
construct the data structures for the operand stack, the execution stack,
and the dictionary stack.

Additionally, stack objects are compound objects such as arrays, dictionaries,
and strings. Related operators include:

stack specific: __endstack, $, dictstack$, execstack$, index$, is$, pop$, push$, count$, clear$, dup$, exch$, move$

polymorphic operators: get, put, forall, type

text representation: cvs, =, stack, __print, ==, pstack

type agnostic operators: def, dup, cvx, cvlit, xcheck, where, known, exch,
load, roll, ...
