But if I don't provide explicit parameters at definition time 
I see little reason why it should be allowed to supply superfluous
parameters at calling time. 
Anyway it is no big deal (arity = -1 works fine in any occasion) and 
it probably worked like this for ages - I just was really surprised when
I finally tripped over this fact.
