Koji Noguchi commented on PIG-5299:
-----------------------------------
Two ways of handling this.
(1) Deepcopy the expressions everywhere so that same expression is not used in
multiple locations.
Or
(2) Delay the removal for expression that is used elsewhere.
I'll try getting a patch with (2) and see how it looks.
