Well, I don't really know Ada, but I think the Ada approach would be to
declare those two functions as generic parameters of the package. Then
when you instantiate, pass in the correct version of the functions along
with the corresponding type.

Conceivably you can also make the types of interest tagged types, and use
inheritance and dispatching to call the correct versions.
