Hi,
lets say you with yo test the expression func
just test
FreeQ[func,Slot[_]]&& func === Head[func[x]]

How many arguments have func[] ? with the definition :
func[x_]:=x
func[x_,y_]:=x*y
func[x_,y__]:=x*{y}
Only solutions with exact one integer number can be accepted.
Contribute and win fabulouse pices.
