Printing the return value requires adding a code or function attribute.
Yes, this requires adding an optional constant code attribute.
The return expression(s)

can be represented like this

or if one has annotations in the definition, then

multiset, which would suggest only integer values, but in a more general
sense, it could be an accumulator of either floating point or integer data.
