[windup-dev] Iteration*Managers

Hi, what's the purpose of having IterationSelectionManager and IterationPayloadManager? I can only see Named~ and TypedNamed. Wouldn't a simple method overload in SelectionFactory be enough for just giving the option of type checking? Or do we assume some other use case for that? Also, the names don't fit - it's not manager, rather some kind of filter, or getter. Also, how about splitting SelectionFactory to VarStack and CurrentPayloadManager? The variable stack and "current payload" seem to be related only indirectly, by concept - at least in the current implementation. And lastly, I'd rename "current payload" to something like "cursor" (resembling DB result iteration) or "current item" or "current element" (which is how XSLT refers to iterated nodes). Payload rather evokes that there's some wrapper around it, which is not. Thanks, Ondra
