Even in this cases I prefer to add the missing arguments
on the callers side. The compiler will flag all code spots
where a call is done. Since it is possible to give a default
value, it is also possible to insert that very same defaut
value on the callers side. But it has the nice benefit of
looking at each call and doing a quick search in the callers
code, if the default is really apropriete. It happend more then
once that I figured out in less then 30 seconds that it was not :-)
