Describe the structure of an object
Describe the structure of an object, recursively.

Additional argument that may be passed to methods; not currently used. |
This supports recursive objects, using recursive calls. Each
level of recursion is indented two additional spaces. List components
are shown with $, slots with @, and attributes with &.
This prints a description; it doesn't return anything useful.
