In the XML parser I wrote, I use an explicit stack, but it doesn't require any special language features. In a dynamically scoped variable, I hold a vector that can be pushed to, and I have words defined (push-xml and pop-xml) that manipulate this stack. The whole thing is either three or six lines of code, depending how you count. It could be abstracted into some kind of declaration STACK:, but doesn't require any special language features.
