Thank you for the correction, Bert. I had always interpreted: "If one follows the 'parent.env()' chain of enclosures back far enough from any environment, eventually one reaches the empty environment." to mean the parent environment was basically synonymous with the enclosure. I re-read ?environment, but I think I am still missing something, so if I may ask a follow up question, would you explain or suggest additional places to look for when/how is the the parent environment distinct from the enclosing environment?
