The dictionary should, of course, contain only the names of immediate 
children. It would be __getitem__ that does the '/' parsing and looks up the 
individual steps. dictionary key completion is not an issue.

Actually: __dict__ can even contain non-pythonic names. You just cannot query 
them by natural naming, but ipython even shows these names in key completion. 
Anyhow: it certainly would be confusing to have non-pythonic names in a 
__dict__ ...
