Description
Let A be a MutableMatrix. Then the following lines seem to have the same effect:
```
B = A
B = copy A
```
... while the expected behavior of the second line is "copy x yields a copy of x".

Research direction
Start by reproducing the two MutableMatrix examples in Macaulay2 and trace how assignment and copy handle the value. Done means that `B = copy A` produces an independent copy of `A`, rather than the same effective object as `B = A`.
