The obvious solution is of course to name the function so that you can tell
what is does! :-)
A function returning a single value, should really RETURN the value and not
update a parameter:
y = year_of_first_marriage();
Having a function lying about its purpose should be caught at its
definition, not at each call of the function:
void will_never_change_any_parameters_honest(int& x) { x = 7; }
is easy to catch early. :-)
