     10It would be easy to implement using the overloading of '+' already present in class Quantity. I suggest something like this if addition is True:
     11
     12def set_quantity(quantity_name, x, addition=False):
     13...
     14if addition is True:
     15    #create new temporary quantity
     16    Q = Quantity(domain)
     17    Q.set_values(x)
     18
     19    quantities[quantity_name] += Q
     20
     21
     22
     23Alternatively, we could make this behaviour the default as quantities are initialised as zero, and have a keyword 'replace'.
     24On the other hand, this could be confusing whenever a code needs to change a quantity.
