Try to peephole at this node and return a better replacement Node. Always returns some not-null Node (often this).

@param i element index @return element being returned; throws if OOB @exception AIOOBE if !(0 <= i < _len)

Change a <em>def</em> into a Node. Keeps the edges correct, by removing the corresponding <em>use->def</em> edge. This may make the original <em>def

Add element in amortized constant time @param e Element to add at end of list @return true

Set existing element @param i element to set @param e value to set @return old value @exception AIOOBE if !(0 <= i < _len)

Add a new def to an existing Node. Keep the edges correct by adding the corresponding <em>def->use</em> edge. @param new_def the new definition, app
