Deprecation in pq.Quantity of the copy argument #1529

@zm711 can you handle this?

zm711 commented 2 months ago

Sure looks like a pretty quick fix. I'll assign myself. I'm busy today, but will work on this week!

@apdavison,

We have a huge portion of our object model that relies on copy vs view of the data. The new default is now always a view, so we have some test failures here because we are testing for copy vs view. Do we want to try to maintain this behavior at the Neo level instead of the quantities level. I think we could just add some deepcopies into the Neo code instead of passing copy to Quantities. I think I will actually move discussion to my issue #1534 for us to strategize.
