[PD-dev] Proposals for object categories

One thing I was thinking about recently is whether we need a hierarchy  
of classes.  In Object-Oriented Programming, there is hierarchy of  
classes as part of the basis of the language.  There is no hierarchy  
of classes in Pd so it seems to me that there should also be no  
hierarchy in the namespaces (FYI: this is contrary to something I  
proposed a while back).

Basically, I mean we should not have a library structure like this:


Instead, it would be a one level namespace, to keep things simple, so  
maybe something like this:


Or even better, have more descriptive, fun and hopefuilly more  
memorable names, like:

This isn't really a proposal of any kind, but more a discussion point.
