[picocontainer-dev] The Visitor on Pico

I've never liked this.  I mean I like the visitor pattern for things  
like ASM, but it seemed gratuitous to shove it into Pico back in the  
day.

Originally Lifecycle's breadth first start() was tied to it.  Then we  
put in a more conventional traversal.

Why don't I like it ?

Consider that child containers can choose different CAF, Lifecycle,  
Montor to parents.  They can also not register themselves with  
parent, so even start/stop does not cascade.
The visitor concept seems to transcend these choices.  Indeed, a  
container cannot block/veto visiting.

I know people use this - can they speak up and give real world  
examples?  Pete ?
