Question: Pi/pi as a positive number

I have a procedure



end proc;


When I type  

smth(Pi);       or     smth(pi);    

I obtain the error message

Error, invalid input: smth expects its 1st argument, T, to be of type positive, but received pi

How can i give the Pi/pi to T  if I want to keep  the T::positive  ?

(evalf is not acceptable.)
