If your object is a value object, you will need to return the modified copy
of the object from within the method.
If your object is a handle object, you do not need to return the object from
the method, as modifying it within the method will modify the object
"referred to" by the variable you passed into the method.

For a more in-depth description of the difference between the two types,
read through this section in the documentation:
