You need 100,000 of these functions in a typical large grocery store.
Ada doesn't support this:
function Price(Pumpkin_Size : Size) return Dollars;
function Price(Milk_Size : Size) return Dollars;
function Price(Granny_Smith_Apple_Size : Size) return Dollars;
Clearly this will be
function Price (Item : Item_Type; Size : Size_Type) return Dollars;
The context associates Size with Item; no need to add more noise.

Exactly; that's why we use Size_Type.
