I wonder if there could be components that would melt/dissolve after use...
... for example a label:
container.add(new Label("xx"));
After use, the label output would become part of container's markup
output at proper position, but there would remain no reference to an
instance of label component.
This would be something like a "passive" component... not just "stateless".
