Detailed Description

Represents the indirection that brings you from a container to an element of the container.
Stored as a string to be used as part of an eval, or as a key to be looked up in a dict.
Each dictionary dereference is individually eval'd since the dict key might have been
garbage-collected
TODO: store string components that are duplicates of strings in the actual system so that
Python will keep one copy and reduce memory usage
