I think that is a good suggestion. The current BCReader and BCCreator 
can be used as a starting point for that.


I had a brief glance at the class structure and the file ideas document 
that John posted. First impression: very ambitious! I will read it more 
carefully, but have one first comment. Generally it is not recommended 
(if you check the cocoa mailinglists) to subclass foundation classes, 
such as NSDictionary. It is better to create a class that has an member 
of such a class. So in this case there would be a BCSequence class with 
a NS(Mutable)Dictionary as a member variable.
