The first question is "Why do you want to do this?"  Is this some 
pre-existing file format imposed by an external system that you can't 
change?  Or are you just looking for a generic way to store nested 
structures in a file?

If the later, then I would strongly suggest not rolling your own.  Take 
a look at json or pickle (or even xml) and adopt one of those.
