Re: actions related to collections

Hi Satya,

Therefore, in your cell line example, I suppose you don't want/cannot 
enumerate the cells, and
therefore express insertion into/removal from the cell line?

You may still want to distinguish the states of the cell line at two 
different instances and
relate them by derivation?
