To make the tradeoff even more explicit the listing below shows the pair 
of "3 extra lines" in option 2 compared to (1).

The number of extra lines in option 2 is defined by following formula:

numberOfExtraLines = 4 + 2 * numberOfParameter

So for 3 parameters it will add 10 lines. This does not seem so bad. So 
now I am torn between (1) and (2) and need additional input.
