I would say the same about Lisp. In fact, each list in Lisp is like its own little stack in Forth. Prepending an element to the front of a list is like pushing onto a stack. Separating the first element from the rest of a list is like popping from a stack. Lists of lists & atoms are like stacks that can contain references to other stacks, as well as atoms.
